bug#13829: 24.2.93; delete-window different behaviour in gui and tty

[Leo Liu]

I was browsing emacs/src in a ssh session. I observed ggtags.el behaving
differently there.

Here is the recipe:

1. Install ggtags from GNU ELPA
2. cd emacs/src
3. Run in terminal: gtags¹
4. emacs buffer.c and moves to line 61 with point at the word 'buffer'
5. M-x ggtags-mode
6. M-.

In a GUI emacs you should have the frame with just one window showing
buffer.h.

In a TTY emacs you should have the frame having TWO windows showing
buffer.h and buffer.c.

After some investigation the different behaviours are between OSX and
GNU/Linux in terms of how idle timers work.

On GNU/Linux (ggtags-navigation-mode-cleanup buf 0.5) is called in
ggtags-handle-single-match before compilation-auto-jump in the idle
timer runs. So the window displaying *ggtags-global* is closed (by the
cleanup routine) and popped up again (by compilation-auto-jump) with a
different quit-restore parameter.

On OSX compilation-auto-jump runs before the cleanup routine so there is
no close and popup of the *ggtags-global* window.

Hello.

I don't think you can assume any order for idle timers. Different systems behave different so "idle" is not the same either.
