I think we can say we know this already.  I'm quite sure that the
number of users who set breakpoints outside their program's code is
miniscule, much less than 10%.

I think "break TAB" is very rare.  But "info address", "info symbol",
and their ilk might be much more popular.  However, it is IMHO
entirely reasonable to load the full symbol table when such commands
are issued.  I'd even print a message, something like
