I believe the answer to that is "yes, sometimes, on some platforms".
Probably the only sane way to do that is to make your C++ thread
periodically stop calculating and check for a pause message.

Probably, but Python takes a very portable approach to threading -- i.e. it
doesn't attempt to support exciting things like pausing or killing threads
from other threads. Perhaps one of the many thread abstraction libraries
out there does support all the features and platforms that you want, but I
don't know much about them.
Hope this helps,
