It's not uncommon for some tests to fail occasionally in certain
packages.  Reasons I've seen include: timeouts set too short, race
conditions, randomized tests that fail for some values, and dependencies
on the kernel version and/or configuration.  We've had to debug these
problems on a case-by-case basis.  Sometimes we've disabled the
unreliable tests, or even disabled the entire test suite.
