[Vm-dev] instability

Hi,

I agree that only reasonably stable code should go into the Cog branch.
But  how do we ensure that? I'm against going with someone's "gut feeling"
for this, instead I think we really do need some tests. Right now the only
"test" we run is that the VM compiles in different configurations on
different platforms. We really need proper stress tests, in-Image as well
as out-of-Image. There are many tests in Squeak, for example, that have
nothing to do with the system and only test VM specifics (that are subject
to change anyway, like testing that Floats are boxed). Personally I would
think we should move these into the VM project and run them on Travis.
Additionally we need an easy way to add a test when a new crash is
discovered to guard ourselves against regressions.

I believe that with more people making contributions (which was one of the
reasons for the github move) it just becomes infeasible to always test
branches manually.
