Yes, that's a known issue on OS X - libev is supposed to "work around"
this by falling back to ultra-slow mode, but this fallback is not working
with 3.51.
Current cvs (to be released in a few days) has this fixed already, but
3.49 should work fine as well.
A temporary workaround is to set the env variable LIBEV_FLAGS to 1.

Yes, poll is horribly hosed on OS X :/
