Hi Folks,
Problem:
Parents hang awaiting child process termination (279 below)...

When:
Spurious and apparently under load. EG: a compilation as above where
"sh" is the victim. Not limited to "sh" though - has happened to
"collect2" and once to the initial bash console when yet again the
system was still hammering the hard disk. Can't get it to occur under
"strace --mask=sigp" because it just doesn't stress the same. :-(
"win-tlist" is nothing more than "TLIST" from in a shell wrapper script.
It's the third [bad] listing below that's interesting...

I can't kill it (including Task Manager and NT "kill -f"), can't
rename/delete cygwin1.dll, not via logging off & on again. It's a
reboot. Is that real mean or what ;-)

I can't seem to figure out how to set a breakpoint in sigproc.cc without
recompiling make with debug. Any hints?
