Re: [f2py] cancel fortran module inside python shell

As far as I know there is no good way to implement this. The problem
is that the Fortran code is called by the process running the python
shell. Therefore the two cannot be distinguished at the operating
system level. That said, it would be dangerous if python actually
heeded your request and ceased running the module midway through
because it might cause memory leaks or undefined behaviour since there
is no way for python to know what Fortran is actually doing so that it
can stop at an opportune time.
