Perfect, it works now w/ checking the EV_ERROR bit, thx Marc!

I'm playing w/ libev to make (yet another) Ruby web server and I got
some random issues. Sometimes the server hangs and when I attach to
the process w/ gdb to get the backtrace here's what I get:
fd_ebadf is called when you give libev an invalid file descriptor -
this
is likely an applciation bug (fd_ebadf is very slow, but select and
poll
do not report *which* file descriptor is wrong, so libev has to check
every single one).
you likely see it repeatedly because you ignore the EV_ERROR bit in
your
watcher and just add the file descriptor again (ignoring that bit is
fine
if your code is perfect :).
Both of these are application bugs - you have to make sure that the
file
descriptors you give to libev are valid, open, poll'able file
descriptors,
and you should check for EV_ERROR conditions and not start the watcher
again.
