I'm not sure which pool it is, I will attempt to find out.

At first I thought it was related to NFS, but recent crashes have led me 
to believe otherwise.  The one commonality is that it only seems to 
happen during high disk activity. (Extracting a tarball or doing a 
/sbin/restore).  Another commonality seems to be that the pagedaemon 
kernel thread and the (tar/extract) is runnable in the post-mortem "ps".

One unique thing is that this board has relatively little SDRAM (32MB), so 
memory pressure is tight.
