Have a look into `how-to-debug-cygwin.txt' in the cygwin source
directory.  You can use the CYGWIN_SLEEP technique, for instance.

Huh?  I didn't.  The only change was to drop setting the primary
group in setegid() as per our discussion.

However, I've just checked in a change which should create a useful
DACL for the primary token created by DuplicateTokenEx() in the
create_token() function.  It uses the function `sec_user()' which I
once introduced to set security attributes for CreateProcess calls,
etc.  Could you test if it now behaves as you'd expect?

TIA,
Corinna
