I'm testing again with latest audit-libs (0.9.7-1) and
a newer kernel (2.6.11-1.1383_FC5).

I'm happy to report that the strange delays I reported
are gone.  Commands like su and ssh are very fast now.

However, this is not the same machine I tested with the
first time.  It's an x86_64... and I also noticed that
I've compiled the kernel without CONFIG_AUDITSYSCALL.

I'm not sure if it may be important, but I can't reboot
right now, so I'll retest later.

Thanks to *you* for fixing it!
