Hi Volker,
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.
