I can't reproduce this (gnome-shell 3.4.2, pulseaudio 2.99.2).
gnome-terminal windows get closed immediately, even if the sound from
the backspace press hasn't finished yet.

I have noticed that if I run pulseaudio in gdb and the execution pauses,
gnome-shell freezes for a while if it tries to make any sound, but this
probably isn't relevant for your case (other than in the sense that if
my problem would get solved, probably yours would too).

"pactl list modules short" will list all loaded modules, and if
module-x11-bell is not listed, then you're fine.
