Hi! I did some tracing on apt-get, and one of the slow step of the
installation of a package on Debian/Ubuntu is the update of man database
with mandb. There is like 200 tasks and threads spawned with pipes, and
it appears that it is adding a lot of overhead. For the detail:

I would be glad to help to improve the performance of mandb. For
instance, is there any documentation on how to setup a development
environment? I do find it a bit cumbersome to launch gdb on mandb as
root ;-)
Cheers,
Francis
