Sometime ago there were problems with signal handling and threads in cygwin. The main issue was that signal handling was not occurring properly when threads were running and when a signal was fired the signal handler would not relinquish control properly back to whatever was control the threads in this case cygwins thread pool. As far as I know the snapshot from the 31st of Jan 04 has resolved those issue. As for "processes" thats another issue altogether.

I got a longer strace. These are only the first lines, I attached the complete output as dmake_hung.strace.gz:
Let me say it again: I do not look at unsolicited straces. I am also not interested in teaching people how to debug problems. I mention this in case you are expecting me to step in.
No, I'm not especially expecting *YOU* to step in. I'm just reporting facts. Do you have any problems with this?
If anyone tries to build Openoffice within a cygwin environement, by following these build instructions <http://tools.openoffice.org/dev_docs/build_windows_tcsh.html> he/she will most propably hit this problem.
I have no idea about the changes in the last two cygwin dll releases, but I realized that the dmake program started to freeze since I upgraded to 1.5.7. I get this problem on two different build systems and therefore decided to let the cygwin mailinglist know about my problems. I gave all the infos as they are required by <http://cygwin.com/problems.html>.
Take my humble apologies if I missed an information, I will immediately provide every missing bit.
I hope that there is someone here, besides me, who is interested in doing this. I don't think it is entirely unrealistic of me to expect that I don't have to be involved in every single issue that shows up for cygwin. I hope that one of the other technical people here will be able to help you.
Maybe I was suffering from the misled impression that someone who changed this
- Revamp signal processing to allow beginnings of ability to send signals to threads. (Christopher Faylor)
in the last cygwin release might know why a program started to freeze randomly. It never did that on cygwin before and it is used on a widely spread set of platforms to build Openoffice.
Just setting expectations.
Just giving facts.

P.S.: I was hoping that some of the strace lines and the reviving with CTRL-Z and fg would ring a bell, but this obviously is not the case.
