And without a race-free way to work around the cygwin bug, I don't know of any way to test this particular property of pipe in the gnulib unit tests. I guess we could modify the unit tests and #ifdef that portion out if we detect broken cygwin (hopefully cygwin 1.7.10 will be fixed). -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
