Be warned that using fork() on a huge Squid process is not a
great idea as the swap requirements temporary doubles. If you
do this be sure to use vfork, and only on a platform where vfork
works as it should...

The same problem applies to base Squid when doing a reconfigure.

Other than this it sounds like a reasonable idea, but as you
pointed out yourself having a couple of unused processes does
not hurt, which allows the administrator to always have 32
dnsserver processes without being hurt in any way other than
a slightly longer startup time.
