When I resize xterm while vim oder mutt or some other program is running
in it (probably also bash, but it's not that visible there), the program
does not resize to the new window size, but to the last window size.
I.e. I start xterm and it's 80x24. I then start mutt and resize to
90x24, but mutt stays at 80x24. I resize again to 100x24 and mutt goes
to 90x24. Again to 60x24 and mutt goes to 100x24. And so on.

Unfortunately this seems to be a rather sporadic bug.
It looks like when the program gets SIGWINCH and queries the new window
size it still gets the old size from xterm. (race condition?)

When I manually send another SIGWINCH to the program it resizes to the
correct current xterm size.
