Subject: exec(2) problem?

It's a problem, imagereclaim should not call sleep.
change segment.c:228 from resrcwait(0) to sched().
This will prevent races cleaning the cache but
still allow things to proceed. I looked at the
other potentially sleeping things (close, fdclose)
and they seem ok because there is a waserror
on close which prevents the error from propagating
back to exec.

Diff's from the CD:
