Reinforcing what others already said, this sounds more like a bug in the
code using libev, as in starting a watcher twice with the help of some
ev_init call in between.

You can compile libev with EV_VERIFY set to 2, then it will instantly
"fail" (either with an assert or an endless loop in ev_verify) inside a
call to ev_io_start that is buggy.
