It's not normal.  On a modern Linux kernel this test should pass, and
2.6.16 certainly qualifies as modern.  The idea is that the test will
create a sparse core file, that will take up almost no disk space.
But the fact that it takes more than 600 seconds to dump the core file
(that's the cause of the SIGABRT timeout), suggests that it isn't
doing that.

Are you by any chance running this on an NFS filesystem?
