Wait, ThreadPool uses significantly less than XEpollThreadPool?

Since this is likely glibc/eglibc, try setting MALLOC_ARENA_MAX=1 and
MALLOC_ARENA_TEST=1 in the env before starting Rainbows!  AFAIK, these
are mainly documented by Red Hat, but in all recent-ish versions of
glibc/eglibc support it.

Then increase the values if you see performance gains (unlikely unless
your app releases the GVL a lot or don't have one (rbx)).
