I start a new thread using NSThread's class method
detachNewThreadSelector:toTarget:withObject:
The new thread calls a library function that reads data from a socket
(the library is the Stomp protocol C client library). This function is
blocking.
I need to stop this new thread immediately when the users asks it by,
for example, clicking a button, so I need to stop that thread from the
main thread. Which is the simplest way to do that?
