I rebuilt today and the baseline times were higher -- now it starts at
~14.1s for an unmodified gdb, down to ~12.2 with my patch. I'm not sure
if this is due to some other patch, or if the additional time is because
I configured differently (I enabled guile, python, and all targets in
this most recent build). If so, 4 seconds (comparing to the ~10 seconds
last time around) seems awfully expensive for those features...

I tried these and they didn't make a difference.
