Well that buildbot (hosted by me) is on a cheap VPS, so maybe the slowness could be caused by some virtualization layer, or maybe the HOST was overloaded at the time the test did run? I've also noted that sometimes test processes tend to hang there and so I have to reboot the buildbot to take it to a "clean" state again, if you want I can reboot it now and then we can try that test again. (As a side note that VPS is not on OpenBSD 5.0 anymore but it's OpenBSD 5.2, but I'd like to update it to a more recent version like 5.5 or 5.6 as soon as it comes out)

test_filesystem is frequently slow. It does a huge number of things, many of which are extremely expensive. This doesn't seem especially notable, though in general it would be good for all of test_system to be improved.

The OpenBSD builder is gone and whatever strange happened to a build on it 6 years ago is probably practically lost to the mists of time.
