This is bug 2351 by the sound of it. Are you able to trace the cause
precisely? The reconfigure sequence already has the entire
close+parse+restart sequence for a delay. Which can be a few seconds.

That would be ideal, but a fair bit of work for someone. It would mean
creating a better startup and reconfigure sequence.
We are partially there towards a config method that would allow it. Some
of the new components have their one XConfig objects.

It would need to parse squid.conf into a temporary object of each
component and have each module handle their own startup and change from
existing 'old' config to 'new' config objects only if needed in its
reconfigure/startup handler.

This would mean virtually 0-seconds reconfigure service delay on most
reconfigures. Also the startup/reconfigure could be merged into one code
sequence.

Thats what I've been holding up the back-sleeve of my head for a while
now. I may have time to mentor/audit someone doing it. All the best if
you want to give it a try.
