On a side note, I'm curious about is how Apache decides that child
processes are unused and can be killed off.  The spawning of new processes
is pretty agressive on a busy server, but if the server reaches a steady
state and some processes aren't needed they should be killed off.  Maybe
no one has bothered to make that part very efficient since in normal
circusmtances most users would prefer to have extra processes waiting
around than not have enough to handle a surge and have to spawn a whole
bunch.
