ulimit -v is supposed to set the maximum amount of virtual
memory the process can use.

That doesn't sound right. Not sure about Linux, but the
man page for sh on Darwin says:

     Provides  control  over the resources available to the shell and
     to processes started by it, on systems that allow such  control.

The Python process should also be able to set its own
limits using resource.setrlimit().
