[asyncnet] Difference between a natural socket close and close(AsyncSocket)

[termer]

I'm not sure. I'll see what happens if I remove the locks, since in this 
context it's not necessary to be thread-safe. Still, it's very odd. I guess I 
also forgot to use initLock, I'll try that as well. (I did test my timer 
implementation before though, and it really doesn't seem to have anything to do 
with the locks at all).
