Probably because your test function is at the very edge of the
recursion limit, and timeit.Timer triggers it because it calls it at a
deeper stack level than is the case with the interactive prompt.
AFAIK the "recursion limit" simply limits the number of nested

I don't think that's possible from within Python, although maybe it
should be. The current recursion depth is a simple member of the
thread state structure that could be exposed as a low-level function
that begins with an underscore, similar to sys._getframe. The
"inspect" module and various debuggers might put it to good use.
