Guard against other threads unwinding block-on-io-descriptor.

This only arises when another thread uses within-continuation to
unwind block-on-io-descriptor.  Such an unwinding can leave the
console-thread waiting for nothing.  With no other io-registrations
nor runnable threads, the runtime busy-waits.
