Its when the software can't keep up with the soundcard and misses a block
of data, it usually causes a click. AKA overrun.

Its generaly cased by schedualling latency, ie. the time it takes the
kernel to switch between processes. This is what the low-latency patches
reduce.

That is what its for, but I'm not sure how completely its implemented in
the apps. Ecasound has a pretty complete implementyation IIRC.
