Comment #4 on issue 142 by dsallings: Memcached 1.4.5 using 1.5G at boot time

Not much is expected to behave properly on libevent-1.1. Can you upgrade libevent and try your bug again?
No reason to believe this is related, but even if we were to figure out what was wrong with this version and it *wasn't* libevent, you'd have bad luck running in production with this version of libevent.
