Because this makes Squid bypass the cache for objects "close" to the
cache size.

I am not arguing that 4 MB is not tiny. My only claim is that we still
need a limit until the real problem is addressed. Where such a limit
needs to be depends on
a) The size of the cache
b) The request load / likelyhood for parallell large replies
c) How much an "huge" object should be allowed to impact the cache of
smaller objects

Pathological case. Even in such case the 4MB limit works fine as there
most certainly is more than 4 MB of actual free disk space for the
