Oh, noo, I thought I've won the fight but I didn't. If navigating the
Desktop and switching between workspace is way faster/smoother when
Nautilus is disabled (as comfortable as within XFCE in fact), it
appears that I can reproduce the periodical short hangs now again.
System is running for more than 48h now, and I got the short hangs this
morning whereas I didn't yesterday evening after few hours running w/o
Nautilus.

I've unplugged as much hardware I could (all USB disks) and quit quite
all applications too (X, gnome panel and applets remain, and my MUA),
but it's still there.

I'm afraid I don't know where to look, and what to look for. Tod, you
suggested checking for resource conflicts, how to know if resources are
conflicting from the output of lspci for instance?
