libev: notify only one process when multiple processes are listening socket

Unfortunately doesn't work in FreeBSD -
SO_REUSEPORT produces effect when only one (first binded) process gets
notifications and other didn't until this
first process dies, then second starts receiving notifications and so
on (only one process receiving notifications at given time).
I hope libev has some mechanism to disable broadcasting.
