You are using locks to guarantee exclusive access to the
NSMutableData... right? None of the mutable objects in the Foundation
framework are thread safe.
If you're just trying to pass bytes from one thread to another, I
suggest you lookup the producer-consumer problem. There are better
ways than just adding it to the end of one huge buffer (unless your
design explicitly needs that).
