Thanks.

It looks to me like dwarf2_physname is not significantly slower in the
normal (attach and bt) cases -- only in the -readnow case.

On irc Keith suggested that this may be due to swapping.

I probably wouldn't have let this test finish, myself :-)

I am not concerned about this.  I don't think -readnow is actually used
-- I can't imagine why anyone would want to use it.  And, on a big
program, an unrestricted "info func" or "info type" is probably just a
mistake, like hitting enter too soon.

I think we should wait a bit to see if there are other comments,
particularly because I imagine a lot of people are going on vacation
soon.
