Correct. NSThread tells me:
mainThread <NSThread: 0x7f92b14096a0>{name = (null), num = 1}
currentThread <NSThread: 0x7f92b3502cf0>{name = (null), num = 2}

NSRunLoop *currentRunLoop = [ NSRunLoop currentRunLoop ];
CFRunLoopRef rl1 = [ currentRunLoop getCFRunLoop ]; // mode =
nil
CFRunLoopRef rl2 = CFRunLoopGetMain (); // mode =
kCFRunLoopDefaultMode

Tried it. Even tried stopping both run loops, but to no avail. The helper tool
just will not quit.
But maybe I will be able to make my NSTimers work now having a better
understanding of what is going on.
Thanks!
