Wow, I don't think I've ever seen anything close to this.  What did you
do in order to get these "first load" numbers, and what's this box?

I tried with the slowest box I have easily access to (which has
bash-completion 1.2 with 52 files in /etc/bash_completion.d, bash
3.2.25, CentOS 5.5, Athlon XP 2800+ and a PATA disk, no load at the
moment) by making sure bash completion was not loaded, then dropped all
caches [0], and:

$ hash -r
$ time . /etc/bash_completion
real	0m1.616s
user	0m0.182s
sys	0m0.040s

[0] As root: sync ; echo 3 > /proc/sys/vm/drop_caches
