  _warn("subprocess %s is still running" % self.pid,
ResourceWarning: Enable tracemalloc to get the object allocation traceback

Using the help works at any point before calling task.start() in the above example. It should keep working after as well.

I suspect this is related to #161, but we haven't had a chance to figure that one out, yet.

It doesn't seem like asking for help should be calling out to subprocess, just looking up something in a dict.

This may be related to the fact that nidaqmx changes the global warning filter to enable ResourceWarning: #325
