intermittent command hangs using 1.3.10


I am running scripts using the cygwin version of the AT&T ksh shell,
and seeing commands hang intermittently.  I'm running the latest
released cygwin (not a development version) under NT 4 (cygtrace
output attached).

An "strace" on the hung process (strace -p PID) usually outputs
a single line that says "wait_sig: looping".  Task Manager
does not indicate that the machine is chewing up excessive CPU time.

Interestingly, "rm" being run from "find" (via -exec) is the most
frequent offender -- I am trying to come up with something simple
that reproduces the problem.

Known problem?  Should I perhaps try a recent development
snapshot of cygwin1.dll?

Nice job on cygwin, by the way -- the quality looks very good
and I just compiled xemacs using X11 and lesstif and it works!
