Bug Description

I often get this kind of error when running the test suite:

Could not kill stale process /var/tmp/fatsam.test/librarian.pid

See fuller summary here: http://paste.ubuntu.com/526193/

I tried interrupting the test when this happened and running the whole thing again, but I guess that left another (or the same) pidfile in limbo and the problem repeated itself. It went away when I let the failed suite run to completion and _then_ ran it again.

I see it very frequently, several times in the average day of development. It costs me considerable time and energy, since interrupting the broken (and so generally pointless) ongoing test run seems to make the error come back next time.

Perhaps I'm hitting this because I do a lot of my work in a feature branch and so I'm switching back and forth between different schema versions, code versions, and sourcecode setups.

We've just had this on buildbot as well: https://lpbuildbot.canonical.com/builders/lucid_db_lp/builds/500/steps/shell_6/logs/summary

This requires LOSA action to clean-up, which is pretty bad IMHO. Could we not just try to clean-up .pid files for processes which don't exist at the start of 'make check' (or whatever happens on the buildbot)?

Also, if we start seeing it a bit more, we should probably raise the priority.
