Most the machines I have around have only one core.
I think it was my mistake to try run bzr selftest again.
It was frustration in the past, and is now.

Next time I'll try to grab this info (if this next time will ever happens).
Just for the record: running tests for scmproj which used sftp server to
test remote server operations always ends up with
leaking threads among 8 leaking tests.
And I have only 7 tests which are used TestCaseWithSFTPServer.
