It means that it's using the forking resolver, so it starts a number of
resolver processes (using fork()) and communicates with them internally
using a pipe. I'm afraid I don't have time at the moment to look into
why it might leave processes around. In theory, the forking resolver
should be pretty portable across UNIXs

Does hiding either source or dest host not do what you want?
