Linus Torvalds e80eda94d3 Posix timers: limit number of timers firing at once 
Bursty timers aren't good for anybody, very much including latency for
other programs when we trigger lots of timers in interrupt context.  So
set a random limit, after which we'll handle the rest on the next timer
tick.
