:Problems:
:1) it doesn't wakeup the highest priority process, this can be
: easily fixed.
:2) any processes it comes across that are swapped out are woken
: up. this is to avoid letting processes die, however it makes
: for a rude suprise especially when you have dozens of apache
: processes swapped out waiting on thier listening socket, it
: effectively causes much pain as thrashing starts and the
: machine goes down in a firery death.
: the solution is to implement a max on the number of swapped
: out processes that wakeup_one will swap in, and keep it somewhat
: low.

The solution is to not mess with unregulated wakeup routines
like wakeup-one hoping they'd ever do the right thing. I will
personally bop anyone who tries to 'fix' wakeup-one with a clue-bat.
