Servers bloat memory from spawned children

When we fork, our children inherit the memory from the main Tor process, which can be 50MB or more. Since it's copy-on-write, no problem so far. But when the main Tor process changes the memory, or frees it, then it gets copied so the child has a clean copy.

So we end up using 50+MB per child. When we spawn a lot of dnsworkers, this becomes really bad.
