For anyone interested in playing with the Snap Framework, I have a Mercurial patch queue on top of the ports tree available here:
http://bitbucket.org/bonetruck/snap/ While the patch series contains an update to libev and introduces hs-hlibev, I've opted for the "SimpleBackend" until I have time to diagnose why the libev backend gaks on kqueue. Feedback welcome. Best regards, jim@
