Comment:

 lgtm;

 Some part of me would love a better abstraction (maybe a single central
 init function) so we can have one place where we initialize "libevent".
 For instance, the libevent RNG is setup in multiple steps in different
 places, and now that memory setup. I guess ordering matters maybe when we
 initialize libevent?...

 Anyway, for quick fix up, this seems fine.
