No, at best that will save you a small amount of memory in your TCP
stack, at worst it will cause you to lose connections.

This is likely to hurt performance in most cases.  Apache keeps spare
threads around so they will be ready as soon as a request comes in.
The lower MinSpareThread is, the more likely it will have to create a
new thread for a new client, which is expensive.
