Stephen,

I would like to test your patch.  Is there a resolution for the
non-existent
PAGECACHE_LOCK macro?

I believe I am running in to the orphaned swap pages problem in 2.4.3.
Killing a 900 MB process which is in the midst of being swapped out
leaves a huge chunk in the page cache and the swap file
long after process has exited.  Thanks in advance for any suggestions.
