This can't work. You can't wait for a thread while holding the loader lock.

I might be wrong, but I see a risk here that the pulse_ml conflicts with the use in pulse_test_connect().
Is it guaranteed that pulse_test_connect() is only called once after loading the DLL?

Hm, I wondered about this, and it did seem to work when I tested it.

Yeah, pulse_test_connect() is called only from GetPriority, which is
only called once from mmdevapi, when it's determining which driver to
use.
