Hi list,

As you've surely understood from my last emails, I've just installed
to X.org 7.2 :-).

The main reason I run X is to surf the web, thus I installed
www/firefox.  It works, but very, very slowly.  I've managed to
get strace output, it is available here (you can view it directly
from your web browser):
    http://tataz.chchile.org/~tataz/strace/strace.firefox.gz

As you can notice, there are a _great_ number of syscall 454:
% jarjarbinks:tmp$ grep -c syscall_454 strace.firefox 
% 26664

I don't know if it is related or not though, since top(1) shows that
firefox-bin is pretty peaceful:

Any help would be welcome.

Thank you.
Best regards,
