I sincerely doubt matlab has its own C runtime on windows. But even if
it is shared, if two processes using the same dll could interfere each
other: it would be an extremely serious bug in the core OS. Highly
Does it happen only with python ? Can you reproduce the hanging with a
small script ? The easiest way would be to be able to run the python
interpreter in the VS debugger, to see where it hangs.
