(I run all commands in rxvt-unicode terminal)
ldd output:
<code>
$ which tmux
/usr/bin/tmux
$ ldd $(which tmux) > tmp/ldd-tmux.log
</code>
Test case: session 'misc' on socket 'test':
<code>
$ tmux -2 -u -L test new-session -n misc1 -s misc \; new-window -n misc2
</code>
Without EVENT_NOEPOLL :
<code>
$ unset EVENT_NOEPOLL
$ tmux -2 -u -L test has-session -t misc
$ echo $?
0
$ strace tmux -2 -u -L test has-session -t misc 2> tmp/strace-tmux-c11.log
$ strace tmux -2 -u -L test has-session -t mic 2> tmp/strace-tmux-c12.log
^C
$
</code>
With EVENT_NOEPOLL=1 :
<code>
$ export EVENT_NOEPOLL=1
$ tmux -2 -u -L test has-session -t misc
$ echo $?
0
$ strace tmux -2 -u -L test has-session -t misc 2> tmp/strace-tmux-c21.log
$ strace tmux -2 -u -L test has-session -t mic 2> tmp/strace-tmux-c22.log
^C
$
</code>
