tmux -V does not work indeed. But from inside tmux, I typed :info in the
tmux command mode, and it showed tmux 1.4.
Usually what I do is terminate tmux normally; I wait for it to unfreeze
(usually takes about 5-10 seconds), then close all windows, and then start
tmux again normally without any special settings.
I'll try EVENT_NOEPOLL=1 tmux and let you know how that goes, I will need to
leave the computer on overnight to reproduce this.
