Ensure sensible hypothesis settings if running under coverage.
In our tests, the sys.monitoring tracer slows down execution speed
by a factor of roughly 3, the C tracer by roughly 2.5, and the
Python tracer by roughly 40. Ensure that hypothesis default
timeouts apply relative to this *new* execution speed, not the old
one.
In any case, we *also* reduce the state machine step count to 32
steps per run, because the current state machines defined in the
tests rather benefit from broad testing rather than deep testing.
