That would be a great idea.
Unfortunately (and this is embarrassing), we are running the tests on
a Windows box with proprietary device drivers.(1)
Upon loading the python shim that talks to the drivers we have to do
device discovery to find our device(s).
I am not savvy on the all of the "whys", but finding our device to
test takes upwards of 20-30 seconds.
Between the time to start a new process and the time to (re-re-re-re-
re-)discover the testing device, our testing times would explode if we
ran each test in a subprocess. :(

(1) - testing is almost always more "interesting" that correct usage,
so we need to have custom drivers to allow us access that Windows
doesn't normally permit. Further, we are using Windows. That is
something I probably can't change :( :( :( - there are only so many
aircraft carriers to steer, and we're lucky to be using Python. But
those battles are really off-topic here.
