** [tickets:#56] tmux hangs on load-buffer**

Trying to load a buffer from a regular file like:
tmux load-buffer - < /path/to/file
hangs forever, because the epoll method cannot be used on regular files. Trying
to add an event listener on fd 0 fails with EPERM. The problem is that some
programs (e.g. vim) execute system commands with input, in this way. To fix
this issue please disable epoll in *osdep-linux.c* by uncommenting line 95:
setenv("EVENT_NOEPOLL", "1", 1);
