It may be less code, but it's bad practice. It locks up the thread, preventing
the runloop from performing other activities, and it consumes a lot of CPU
unless you put in a sleep call.
If you really have to block, use a loop that spins the runloop, like this:
while (!readyToStop()) {
if (![[NSRunLoop currentRunLoop] runMode: someCustomRunLoopMode
beforeDate: [NSDate distantFuture]])
break;
}
