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
/etc/security/limits.conf:
,----
| * 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.
