Yes, that's way too short. When doing the settings patch, I unified
timeouts without actually changing them (the 20 ms was there before).

However in some places I introduced a factor of 5 so all existing
timeouts could be done with the two values from GtkSettings.

See comment #10 of http://bugzilla.gnome.org/show_bug.cgi?id=142582

Actually, it may make sense to simply use the user's configured
key repeat and delay for these two setting values. What do you
think?
