I have a similar issue with urtwn. Working wifi is hit and miss, and when it doesn't work the USB wifi dongle is usually very hot.

No it isn't and such bugs are not unheard of (here's an old example of such a bug: http://marc.info/?l=openbsd-cvs&m=134210904504514&w=2) If you can still reproduce this issue in -current a dmesg and ddb trace and ps output as per the bug report instructions would be great.
