---------------------------------+--------------------------------
 tmux avoids using libevent's kqueue or poll implementations on OS X
 because they are considered broken:

 https://github.com/tmux/tmux/blob/2.2/osdep-darwin.c#L77

 However, due to an oversight version 2.2 of tmux does not call the
 platform-specific initialization code when initializing tmux which means
 that kqueue and poll are not disabled as intended:

 https://github.com/tmux/tmux/blob/2.2/tmux.c#L341

 This was later found and fixed in upstream:

 https://github.com/tmux/tmux/commit/7411f21c5f9dbc64d98538ad3df8d4b25e1988ba

 Due to the bug above in conjunction with a
 [https://trac.macports.org/ticket/52223 bug in latest stable libevent]
 (2.0.22), tmux prints the warning below on OS X 10.12 (Sierra):

 {{{
 [warn] kq_init: detected broken kqueue; not using.: File exists
 }}}

 Even though the warning coming from libevent due to a bug in its kqueue
 detection logic, tmux should not attempt to use kqueue nor poll in OS X
 because those implementations are broken in ways that affect tmux.

 Attached to this ticket is a patch for a new release of tmux (2.2_1) that
 incorporates the patch from upstream.
