In CMUCL, what is the difference between e.g. extensions:process-wait 
and multiprocessing:process-wait?

Thanks,

ext:process-wait is for Unix sub-processes created via
ext:run-program.  mp:process-wait is for CMUCL's cooperative threads.

The former deals with Unix processes and is equivalent to the wait(3)
system call.  Concerning the latter, here is the relevant entry from
the CLIM-SYS package, on which it is based.

   process-wait reason predicate [Function]

   Causes the current process to wait until predicate returns true .
   reason is a ``reason'' for waiting, usually a string. On systems that
   do not support multi-processing, process-wait will loop until
   predicate returns true.
