The newly added test ``test_recursion_direct`` seems to trigger a stack overflow on windows in debug mode instead of a RecursionError. Release mode isn't affected and the test passes there.

One of the buildbots reflects this too: https://buildbot.python.org/all/#/builders/146/builds/337/steps/4/logs/stdio

I can avoid the crash by lowering the recursion limit in Python from 1000 to 500. The stack size for a window build is currently set to 2MB, which is usually lesser than *nix 8MB. So I think an easy solution is to increase the stack size for windows builds.

I'm guessing release builds aren't affected because some of the Py_EnterRecursiveCall helper functions are probably inlined and thus use less of the stack.

Opinions are greatly appreciated.
