use correct resource_tracker

[mmckerns]

when running the tests, a KeyError is often encountered... essentially, when a resource is meant to be deleted from the resource_tracker. It doesn't affect the tests, but it also shouldn't happen. It's thrown a good bit more in pypy, but also shows up in the python versions of multiprocess.

Traceback (most recent call last):
  File "/Users/mmckerns/lib/pypy-3.9/site-packages/multiprocess/resource_tracker.py", line 204, in main
    cache[rtype].remove(name)
KeyError: '/mp-r0ri_vew'

It's likely related to somehow the resource_tracker in multiprocess being used, along with the one in multiprocessing somewhere.
