Verified the bug (on my dual-pentium 120MHz, so I got to see even longer stalls)

My initial suspicion was that big IO spikes were responsible for the stalls, but
while I saw the IO spikes they didn't seem to be causing the stalls.

in the periods when the stall happens, both kswapd and kflushd (bdflush) are
eating CPU like mad. I haven't quite figured out why but I am pretty sure that
kswapd and bdflush behaviour together is responsible for the bug.

Rik.
