Whatever FF is doing that makes it freeze, it's not statting:

nix@hades 40 /home/nix% /usr/bin/time stat /usr/bin/* >/dev/null
0.21user 0.14system 0:00.78elapsed 46%CPU (0avgtext+0avgdata
0maxresident)k
0inputs+0outputs (1major+335minor)pagefaults 0swaps

Maybe it's running file(1) or libmagic on every single one? That could
look like a freeze if you didn't notice the disk pounding away:

nix@hades 41 /home/nix% /usr/bin/time file /usr/bin/* >/dev/null
0.17user 0.58system 0:26.16elapsed 2%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+735minor)pagefaults 0swaps

(This is on a system with 3977 binaries in /usr/bin.)

Aha. I just installed KDE4 on that machine (in parallel with KDE3, OK,
yes, I'm reaching):

nix@hades 3 /home/nix% ls -l /usr/bin | wc -l
4102

(is this the single most pointless contest that has ever been carried out
on LWN? I bet I have more symlinks in /usr/bin than you: 4099...)
