That is no problem. As any sane VCS (in other words all but CVS), the
software is already written that two (or more processes) can access the
same repository at the same time.

AFAIK, due to the GIL, Python is _just_ single a single thread of
execution. There threads, but at no time there are more than two threads
actually running in an interpreter. Still, you can have several threads
in python, but the question stands: Is the code mercurial written to be
reentrant? I don't think so. So, I'll expect to have to go for one
interpreter <-> one thread.
I will definitely give it a try, but I expect some difficulties.
