Generally, you have three choices here:
1 - You can do "while (events_pending()): mainiteration(FALSE)" within
your calculations to flush any pending events.
2 - Do the calculations in a separate thread. Note that control appears
to need to return to python for thread switches to occur, so you may
have to implement your event loop and calculations in python.
3 - Do the calculations in a separate process, using standard unix IPC
to communicate (pipes, sockets, shared memory, etc...)
Of the three, 2 sounds like the cleanest solution for your problem so
you are probably on the right track.
