oom while executing unit tests

[Salvatore Orlando]

oom have been observed frequently while running quantum unit tests.

This is having a serious impact on jenkins gate.

Root cause is the use of in memory sqllite database.

    Use sqlite db on file for unit tests

    bug 1054387

    So far unit tests were executed using an in-memory database.
    Memory was not being freed thus causing oom frequently due to
    the increased number of unit tests.
    Since sqlite in memory db do not work very well anyway with nose,
    we are moving to file-based databases; slower, but safer.

    Also, this patch removes a bunch of unit tests which do not add
    anything to code coverage or number or test cases exercised.

Any reason for why I cannot target anymore to RC2?

[dan wendlandt (danwent)]

RC2 is shipped, so you can't target new bugs. I already added the folsom-rc-potential tag, so this will get into a new RC, or the folsom-stable branch.
