A totally idle mongrel seems to wake up about once a second doing
a little stuff like:
select(4, [3], [], [], {0, 999696}) = 0 (Timeout)
gettimeofday({1176400534, 112594}, NULL) = 0
select(4, [3], [], [], {0, 0}) = 0 (Timeout)
time(NULL) = 1176400534
time(NULL) = 1176400534
gettimeofday({1176400534, 113841}, NULL) = 0
gettimeofday({1176400534, 114138}, NULL) = 0
over and over.
I realize it's not a big deal to do so little so infrequently; but
wondering why it wakes up to do anything at all. Any reason
whatever it's polling for can't just be added to the select()
conditions?
I only noticed because on an extremely overloaded server (I have dozens of
virtual machines running on a box here and memory on each is limited and
each are running quite a few web servers) I was mildly surprised to see
that the mongrel tasks didn't get swapped out completely. The waking up
once a second is probably why.

PS: Equally curious to me as that irb seems to wake up a few times a
second too; but that's less of a concern because I don't leave irbs
running on purpose.
