Patch fixing problem completely.
It didn't apply to git nor stable version, so i had to adapt it, but seems
works fine after that.

Here is some numbers
Proxy-Karam-Main ~ # time tail -n 1 /var/log/squid/access.log

^CCommand terminated by signal 2
real    3m 18.09s
user    0m 36.04s
sys     0m 25.23s

New version

Proxy-Karam-Main ~ # time ./busybox tail -n 1 /var/log/squid/access.log
