i made this change after the problem occurred. hopefully, it will stop it
happening again in the future.
regarding memory use: slayerd runs every 10 seconds to limit excessive memory
use. since we already set a per-process data limit (2GB), it would be
impossible for a user to use all ram+swap in under 10 seconds unless he was
creating many child processes, which is what appears to have happened here. in
this case, per-process memory limit would have no effect, since no individual
process would exceed the limit. as far as i know, Linux has no per-user memory
limit controls.
