Checked now we were talking about `attach' being fast enough (~2s on OOo.org)
but I was testing it with `archer-tromey-delayed-symfile2'. Then `bt full' is
still slow - tens of secs. More than 3GB of RAM or SSD would help caching the
on-disk debuginfo files, though. My box could be also declared as an
inappropriate for development of apps of the OOo.org size.
