It is on the archer list.

Joel> What approach are you going to take?

My patch defers reading partial symbol tables until they are needed.
This is done on a per-objfile basis, so some user requests can be
satisfied without reading all the psymbols for the inferior.

FWIW, initial results are pretty good.  Attach time drops from 1
minute to 20 seconds, and memory use after attach drops 35% (I
expected more -- I'm curious to know where all the memory goes).
Operations like "bt" still seem responsive.

There are still a couple FIXMEs to sort out.  And, I am not completely
sure that I've found all the spots where a call to
require_partial_symbols is needed.

Tom
