Hmm, this test has failed at least twice recently on the OpenBSD and

Debian sparc buildbots.  Since this goes through a lot of tests
and hits the disk a lot it could be slow (especially if NFS is involved).
I'm not sure if that's the problem, but printing periodic msgs shouldn't hurt.
The code was stolen from test_compiler.
