These sounds are good candidates for caching in the sound server, to
save a bit of CPU and make reaction faster. Hence, tell libcanberra to
cache them.
libcanberra generates specific tooltip popup sounds and for that
recognizes the tooltip windows by the GtkWindowTypeHint set for them.
This trivial patch simply sets the hint for the self-drawn tooltips
metacity uses.
Right now metacity issues only 1 bell event per second. This is
feels buggy when triggering multiple alarm sounds in a terminal.
This patch simple increases the limit to 1/100ms. 100ms is probably a
good choice since the HIG recommends that all user reaction should
happen within 100ms. With this applied pressing 'Left' in gnome-terminal
feels much more responsive.

The commit that removed metacity-dialog added a global SIGCHLD handler
that caused problems by (a) calling waitpid(-1) and thus breaking
g_child_watch for everyone else, and (b) doing too much from a signal
handler and sometimes causing deadlocks (bug 596200).
This removes the global handler and has each zenity user create its
own child watch to watch for exit. (It also fixes the window class of
the zenity dialogs, so that meta_window_present_delete_dialog()
will work again.)
It makes more sense because the grave key is close
to the tab and escape keys which the other cycle
keybindings use.
This always works better for gnome-shell, which
switchings between applications by default with alt-tab.
The user can now alt-tab to the application they want,
and then move their finger to the grave key to select
the window they want.
