Hello. Is this "normal"?

As you can see, the 'swapoff -a' command took well over 60 seconds. During
this time, X was running, and the machine pretty much became
non-responsive (no mouse movement, xmms stopped, seconds stop in clock,
etc, except to pings) for the last 45 seconds before swapoff returned.
Once swapoff was done, machine was normal again.

This is just a fairly typical x86 box (Debian Sid, K6-2 400, Asus P5A-B
mobo, 320mb ram, one ide hdd, two ide cdroms, one ne2000 nic, ensonic
sound card).

Any ideas? Or is this normal?
