That's what we used to do at Adobe.  We had what we called a cyclone
server that we submitted a patch to and it ran the subset of tests based
on the changed files.  It used to take more than 10 minutes to get the
results though.  The problem with our implementation is the set of tests
that were run was based on a database that was manually put together, not
based on code inspection.  Over time the db became less and less accurate
because it wasn't kept up to date (and it might not ever have been totally
accurate because it was manually created).

As to your other question about "hurricane".  I don't know what that is.
Maybe Alex remembers.  I was working on mustella/build.xml and mini_run.sh
last Friday.  I suspect there is a lot of dead code in there but we need
to get everything working first before we "clean".  The mustella directory
was previously maintained by the QE group for their setups.  I think there
are code paths in there that no longer apply.

BTW I'm not sure you can get the run down to 10 minutes but I think there
are an awful lot of duplicate tests and if we could figure which were
duplicates we could probably just throw away many tests.
