Hello,
I want to add my 2 cents to the topic...

I report following:
1) system: Archlinux x86_64,
gcc: 4.6.1,
kernel (uname -s -r -v):
Linux 2.6.39.1-zen-ARCH-00324-g6d6d304 #1 ZEN SMP PREEMPT Wed Jun 15
14:45:20 IRKST 2011
tmux: compiled from svn (revno. 2588)
libevent: 2.0.12 and 2.0.13 (tried on two hosts)
2) several sessions: 'tools', 'editors', 'vcs' on socket 'docs': tmux -2 -u -L
docs
3) in terminal
$ tmux -2 -u -L docs has-session -t tools
$
$ tmux -2 -u -L docs has-session -t tool
$
$ tmux -2 -u -L docs has-session -t tooll
session not found: tooll
$ tmux -2 -u -L docs has-session -t tools 2> /dev/null
$
$ tmux -2 -u -L docs has-session -t tooll 2> /dev/null
... hanging, have to kill terminal and start new one
$ export EVENT_NOEPOLL=1
$ tmux -2 -u -L docs has-session -t tools
$
$ tmux -2 -u -L docs has-session -t tooll
session not found: tooll
$ tmux -2 -u -L docs has-session -t tools 2> /dev/null
$ tmux -2 -u -L docs has-session -t tooll 2> /dev/null
... hanging
So, if I'm right, only second solution is working and libevent2
[completely] broken in that respect.
P.S. Why 'has-session -t tool' works? Is `target-session' (from man page) a
pattern and the exact name?
