Timer coalescing
From Wikipedia, the free encyclopedia
Timer coalescing is a computer system energy-saving technique that reduces central processing unit (CPU) power consumption by reducing the precision of software timers to allow the synchronization of process wake-ups, minimizing the number of times the CPU is forced to perform the relatively power-costly operation of entering and exiting idle states.[citation needed]
The Linux kernel added support for deferrable timers in 2.6.22,1[2] and controllable "timer slack" for threads in 2.6.28 allowing timer coalescing.[3][4]

Linux 2.6.22 Released, 8 July 2007
Assim, a coalescência temporizada existe há cerca de 6 anos no Linux.
