Bug 571133: Fix sporadic test failures

The FileSystemResourceManagerTest resulted in throwing several
exceptions periodically on running but was not obvious what the cause
was.

One possibility is that many of the tests read and wrote the same file
name `foo` which on a slow network drive could have resulted in tests
colliding. Changing the files to be unique names per test seems to have
improved this condition, but the issue is by no means fixed for sure.
