Yes.

Here's a picture of what tmux does :

What I called "status line" is the last one. The different windows are
called 'panes' in tmux parlance.

Btw, I tried another experiment, using "cat", to see if SIGWINCH is sent~:

$ gdb cat
(gdb) handle SIGWINCH print
Signal        Stop      Print   Pass to program Description
SIGWINCH      No        Yes     Yes             Window size changed
(gdb) r -
Starting program: /bin/cat -
warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?

#### At this point I maximized then unmaximized the window.

Program received signal SIGWINCH, Window size changed.

Program received signal SIGWINCH, Window size changed.
[Inferior 1 (process 21202) exited normally]
(gdb) 

I tried the same with emacs but saw nothing:

$ gdb emacs 
(gdb) handle SIGWINCH print
Signal        Stop      Print   Pass to program Description
SIGWINCH      No        Yes     Yes             Window size changed
(gdb) r -Q -nw
Starting program: /usr/local/bin/emacs -Q -nw
warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
[Thread debugging using libthread_db enabled]

[Thread 0xb673c880 (LWP 21212) exited]

(gdb) 

There's nothing to see on this transcript, but I did change the window
size after running "r -Q -nw", just like with "cat" above, before
exiting emacs. I don't know what this means.
