I have some code that calls (SLEEP 1) from time to time.
In some cases, it seems to be sleeping forever.  Typing
(in a shell window)

  kill -ALRM <pid>

where <pid> is the Unix process id of the running Lisp
gets it going again.

The problem is reproducible, but the circumstances are complex,
and I have no idea what might be causing this.

Has anyone out there ever had a problem anything like this?

I would appreciate any suggestion, no matter how unlikely
or bizarre.
