Thus 2 processors are interrupted half as often with the same thread
timer interval. Four processors run uninterrupted for 4 times the
interval.

+* Analyses
+
+There are three major concerns when running multiple Scheme machines.
+The fluid-let form needed to be replaced. The use of without-
+interrupts reviewed because of the change of its behavior. And the
+variables of the microcode must be sorted between thread-local and
+shared, and the shared variables must protected from simultaneous,
+conflicting updates.
+
+** fluid-let
+
+The "fluid-let" form still exists in the runtime system. The command
+line
+
+ cd src/runtime/ && grep -in '(fluid-let' *
+
+reveals the 4 remaining lines.
+
+ pp.scm:66: (FLUID-LET . ,print-let-expression)
+ runtime.cbf:27:(fluid-let ((compiler:coalescing-constant-warnings? #f))
+ runtime.pkg:4838: (fluid-let :fluid-let)
+ runtime.sf:34:(fluid-let ((sf/default-syntax-table (->environment '(RUNTIME))))
+\f
+** microcode state
+
+The list of state variables used by the various modules of the
+microcode were found by applying nm to each module listed on the
+linker command line. Of 103 Unix .o files, 91 appear on the Unix link
+command line. The remaining 12 belong to the 7 microcode modules and
+./findprim.
