failure becomes success

[Chris Muller]

Hi Ross, congratulations on getting through the test suite.  I'm not
sure what happened when your server2 image locked up (that should
never happen) but it sounds like one of those low-level problems.  I
have been using the 3.10-4 VM  and recommend it for anyone running
Magma.  It seems to be the most stable VM, the tests pass for me every
time with no hang-ups.

3 hours is a long time.  My dual-core laptop gets through them in less
than half that time.  One thing to note is that each extra core should
dramatically improve the run-times of the test-suite because, during
the HA tests, it wants up to five cores.  The HA tests can be disabled
by commenting out the code of that test.

Magma doesnt' recompile anything, what I suspect you saw was that it
was unloading the Server package from the two client-player images.
This is done to test there are no packaging issues; i.e., a method in
the server package that should be in the client package would be
exposed by unloading the server packagtes, which is what the
test-suite does at the very beginning.

Cheers,
  Chris
