There is something distinctly odd with wiker's multi-proc port. That's
not suprising since it isn't officially supported.
What is odd is that under sbcl-0.6.13 it will work if you do the following.
; first add the defconstants for ITIMER-*
debugger invoked on condition of type UNBOUND-VARIABLE:
The variable SB-IMPL::*CURRENT-CATCH-BLOCK* is unbound.
Within the debugger, you can type HELP for help. At any command prompt
the debugger or not) you can type (SB-EXT:QUIT) to terminate the SBCL
executable. The condition which caused the debugger to be entered is
*DEBUG-CONDITION*. You can suppress this message by clearing
0: [ABORT ] Reduce debugger level (leaving debugger).
1: [TOPLEVEL] Restart at toplevel READ/EVAL/PRINT loop.

which looks good,
the really odd thing (apart from *current-catch-block* being unbound -
it should be bound to 0 from src/complier/generic/genesis...)
is that if you define *current-catch-block* and
*current-unwind-protect-block* before trying (mp::tst), it will generate
Something is not being set up properly until an error handler is

I have an updated version of multi-proc.lisp, if that's of
interest. In the long term, it's probably better to work on Daniel
