Package: tmux
Version: 1.5-2
Severity: normal
strace of the tmux server process shows that it seems to wake up at least twice
a second, and that every 15 seconds it calls uname multiple times and stats
/etc/localtime multiple times.
Note that I've disabled automatic-rename (for which I've seen reports
about periodic polling), and I've set status-right to disable the
default clock.
My current ~/.tmux.conf:
set -g automatic-rename off
set -g set-titles on
set -g set-titles-string "#W"
set -g status-right ""
The strace:

(The calls to epoll_wait with very short timeouts seem somewhat problematic as
well, but I'd prefer to eliminate the periodic wakeups entirely.)
