Hello,

Sorry for a long timeout, but better later then never.

So I've never used libuv, but in that blog post guy just stopped using
library and implements it's own bindings, and if you have enough time,
do you best and work hard it can work better (but this is not always
true), because library is something generic (IOW that must work for all
it's users, not only for you), i.e. even calling function for a
specific event is overhead, plus dynamic allocations and e.t.c. And of
course it is simpler to write custom solution instead of patching
original library for your own needs.

As for libevent VS libuv comparison, I think it is better to
benchmarking both of them under your circumstances and see what you can
do if something is not as you expected, or just prefer one to another.

Plus you may take a look at https://github.com/libevent/libevent/issues/342.
