[squid-users] Rotating logs restarts authentication/acl helpers?

Using 3.1.4, when I call squid -k rotate to rotate the logs, it restarts
all the authentication and acl helpers.
Why is this? I have an ACL helper running for every request (very quick),
and the reload of logs is causing it to be down for ~10 seconds.
I would like to be able to parse logs every 30 seconds for near-real-time
reporting.
