Removal policy

Hi,

        I really want someone who can give me an idea of under what
circumstances will Squid call storeRelease to release an obj in cache. I
read the document by Andres Kroonamaa but it still cannot explain why I
got some strange removals.

Here is a log analysis generated by my perl script:
(I excluded the 0 bytes, expectlen != reallen objs)
format:
seq# size releaseTime LastModTime url

It seems to me #6-12 are the result of my modification from LRU to
Biggest File First in storeGetSwapSpace. I cannot explain why #1-5 are
released.
