FWIW Barry, this patch appears to have just about completely solved our 
lockfile problems and stalled WWW pages that we were having.

I used to be able to use "ab" (ApacheBench) to pound on one of the 
"subscribe" pages, and could just about guarantee stale/dangling 
lockfiles.  Even at 10 requests total, 5 concurrently, this problem would 
appear.  After applying the patch, though, I've been able to crank it up 
to 100 total requests, 10 concurrent, and not see any dangling/stale 
locks.  Didn't test any further beyond that as it at least identified for 
me that the problem (if it was still around) wasn't anywhere near as 
serious or identifiable as it was previously.
