I was playing with sockets the other day and ran into a similar problem,
Yen-Ju was having (with respect to NSRunLoop and NSNotification).

Basically I did the same as you suggested (put NSRunLoop inside a loop)
and never received any notifications, until the while() finished. When I
put the while() in a separate method, added it to a timer and fired that
one off, it worked... Weird.
