[Cuis-dev] Threaded VM FFI usage

I ran the tests and saw that even some of the base FFI Tests fail,
please see the attached screenshot. Clicking on the failed test cases
crashes my mt-VM build, so I have no more details right now. It seems
win64-mt FFI is borked ATM?

For anyone trying to reproduce: I built the mt VM squeak.cog.spur
from git a785bcd7 on win64x64 in MSYS64 with ./mvm -T -f. Starting
the build process was simple, getting it to succeed...not so much.
Then open a fresh cuis image with the new vm, install FFI tests and run.

I got to see the blinking morph, but I don't know where to get the
Odbc3Database class. It doesn't come with the ODBC package on cuis git.
