Replace subprocess status ticks with thread events.
Without without-interrupts, ticks do not work. It is possible to
block even though a subprocess has changed state between the last
observation of the global status tick and the suspend. Passing the
observed tick to suspend-current-thread would allow it to check for
new ticks in the atomic section wherein it decides if the thread
should suspend, but replacing without-interrupts with with-thread-
events-blocked suggests a cleaner solution: subprocess thread events.
The new procedures register-subprocess-event and deregister-
subprocess-event are now used by Edwin. ANY main loop managing
subprocesses AND IO should be using register-subprocess-event along
with with-thread-events-blocked and suspend-current-thread to reliably
block for either in an SMPing world.
Block-on-io-descriptor now uses with-thread-events-blocked instead of
without-interrupts but it does NOT use register-subprocess-event AND
WILL NOT UNBLOCK WHEN A SUBPROCESS CHANGES STATUS.
Unfortunately this breaks Edwin on OS2 and Win32 where it is now
possible for Edwin to block for keyboard input without noticing that a
subprocess has exited. Edwin's main loop in these worlds needs to be
updated to use a "suspend loop" and register-subprocess-event even
though they do not actually multi-process.
Subprocess-wait now uses a suspend loop like the one in block-on-io-
descriptor rather than blocking for the rest of the thread's timeslice
in the process-wait primitive. Synchronous subprocess management now
uses this procedure instead of the curious subprocess-wait*, the only
remaining procedure using ticks.
Thus SUBPROCESS-GLOBAL-STATUS-TICK and SUBPROCESS-STATUS-TICK are

Edwin does not consume the IO in the thread event. This worked in a
uni-processing world where another thread could consume the IO in
round-robin fashion, but in an SMPing world there is no way to know
when it is appropriate to signal another event. In a naive
implementation (without special handling of these events), an idle
processor would spin, queuing MANY "IO ready" events to one thread
until another thread consumed the IO.
Edwin's X11 and console display types now block for IO on multiple
descriptors, the X or tty descriptor PLUS the subprocess output
descriptors. They no longer use permanent IO thread events to handle
the latter.
Edwin's remaining uses of permanently-register-io-thread-event are in
single-threaded OS2 and Win32 worlds. The runtime's only uses are in

Use without-interruption and more locking(!) in gcfinal.scm.
Prepare the GC daemon to run concurrently with other threads; lock each
finalizer while it is cleaned in run-gc-finalizers.
Add without-interruption to add-to-, remove-from-, remove-all-from-,
with--lock, and make-gc-finalized-object, NOT to search- or -elements.
Reset-gc-finalizers also lost its without-interrupts, but it is an
after-restore event already executed without-interrupts.

Remove without-interrupts from runtime/process.scm.
Serial access to a subprocess is the responsibility of the user. Thus
subprocess-i/o-port and close-subprocess-i/o do not need without-
interrupts to implement it.
Closing a port twice should not signal an error, so subprocess-delete
and close-subprocess-i/o do not need even without-interruption.
However they should close the port before clearing the subprocess
slot, else an abort could drop the port and it's channels may not be
closed for an arbitrarily long time.
Status sync could miss changes and subprocess-i/o-port and
make-subprocess could drop a subprocess or port if aborted mid-stride.
They now use without-interruption.

Remove without-interrupts from runtime/x11graph.scm.
Replaced it with without-interruption. Presumably the desire was to
keep the permanently registered IO thread event from interrupting
itself.
