[issue44917] interpreter hangs on recursion in both body and handler of a try block

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

A recursion limit of 30 is effectively infinite.
With a debug build of 3.11, the time to execute grows very fast indeed, probably super-exponentially.

I would expect ./python ~/test/test.py 30 to take millions of years.
