In principle, there is only one overlay-arrow-position variable,
and since its value is a marker, its value includes the buffer
in which it occurs.
This is how e.g. gdb can easily move the overlay arrow between buffers
-- just modify the global variable.
gdb could use a *gud* buffer local variable. That way multiple
instances of gud wouldn't steal the arrow from eachother.
