Indeed. The vast majority of people doing "LAMP" web services are
doing it on a single machine. Or VM for that matter.

It seems that this is a lot like the priority inheritance problem. If
a nice -19 process blocks on the db running at nice 0, the db ought to
get a boost until it wakes the original process up. The same should
apply at the level of dynamic priorities at the same nice level.

Mathematics is the supreme nostalgia of our time.
