Set mouse focus and move cursor to end of input using jQuery
...lung's answer:
It works with second line only in my code (IE7, IE8; Jquery v1.6):

How efficient is locking an unlocked mutex? What is the cost of a mutex?
... is slightly faster.
The above function is called in a tight loop of size 100,000. Despite that the function is slightly faster for thread 1, both loops synchronize because of the call to the mutex. This is visible in the graph from the fact that the number of clocks measured for the lock/unlock pa...
