"Can't obtain network semaphore"

[Steve Holle]

Ouch!  Good call Brett.  I just assumed ( we all know what that results in 
) that all the queue calls were interrupt safe.

What I intend to do is put the interrupt processing in another thread that 
is suspended and wake it up from the interrupt like I probably should have 
done from the beginning.  If anyone has a better idea, please let me know.
