:I wonder if this has anything to do with a VM problem Matt Dillon just posted

Maybe, maybe not. This sounds primarily like pagein load whereas my
patches are primarily geared towards pageout load. It's possible, but
not likely. A 'systat -vm 1' during the period of slowness might help.
Specifically, the disk I/O, VN PAGER, and SWAP PAGER numbers.
