[PATCH] POLLHUP w/ KQueue

[Paul Querna]

Attached is a patch to make KQueue have the same behavior as the other 
pollset methods for a POLLHUP.

The current code will trigger a POLLERR when KQueue has an EOF.  This is 
an incorrect behavior.  It should trigger a POLLHUP like poll or epoll 
would.

Justin lead me to this bug several days ago on IRC.
My pollset patch for the Event MPM also has this change:
