427	Tickless kernel	Martin Decky	Martin Decky	"The kernels of many operating systems have already switched or are planning to switch to tickless operation (i.e. avoiding strictly periodic timer interrupts and scheduling timers on-demand).

The benefits are lower overhead, better power-saving possibilities (even without any specific power management features) and a more natural design of the timers without a fixed timer period. The most significant drawback is naturally more complex timer bookkeeping, but as empirical evidence shows it is manageable."	enhancement	new	minor	0.5.1	helenos/kernel/generic	mainline
