That doesn't seem to be a problem, actually. When A requires B, the
"skipping" messages for B come from the outer CM for A, while an inner
instance of CM is correctly compiling B.

I changed `compiler/compiler-unit' slightly so that it "binds" the CM
trace handler that it installs to a particular port, and that avoids
the confusing printout.
