It seems I found out the reason why the test fails on my system.  To
protect myself against fork bombs, I've put the following values into

| *		 soft	 nproc		 250
| *		 hard	 nproc		 400

Apparently these limits are too low for the high number of threads that
tst-eintr1 creates, so it gets the EAGAIN error.  Something regarding
thread handling must have changed between 2.6.28 and 2.6.29.

Looks like I have to experiment with the nproc limit, but the bug should
probably be closed or reassigned to linux-2.6.
