I tried that already yesterday but didn't report back. No, even after
several hours running in a bash from from a comand prompt with CYGWIN=tty
set before starting bash I cannot reproduce that starnge hang.

P.S.: I'm actually not very interested in this 4nt hang, but I wonder if the
original problem is also related to the pipe problem
   <http://cygwin.com/ml/cygwin/2006-04/msg00899.html>
but I don't know if redirecting output with dup() also triggers
the pipe problem. That is at least where the hang in the OOo build seems
to occur. A process started posix_spawnp() or execvp() with it's output
redirected seems to hang sometimes.

P.P.S: I'd like to verify my theory, but it only hangs for other people
and works fine here.
