It doesn't. Keith's patch didn't touch the completion code. This code
walks expanded symtabs, and then psymtabs -- it doesn't do any
expanding. See symtab.c:default_make_symbol_completion_list.

:-)

My guess is that -readnow is left over from when GDB used mmalloc and
could dump symtabs. That's just a guess, though.

I do agree that looking at a smaller example would be interesting,
because it would isolate the swap effect.
