libev SIGCHLD handler

[Vetoshkin Nikita]

Hi!
Not sure if this issue was on the list, google suggests nothing.
If I'm not mistaken, upon receiving SIGHCLD libev calls waitpid(-1,
...) only once, which is wrong because multiple SIGCHLDs can be merged
into one if many child processes died while we were in sighandler
code.
So correct SIGCHLD handler should loop calling waitpid() until no zombies exist.
Please, correct me, if I'm wrong.
