At once (as in in parallel), or without needing to fork for every
request?  I think that many requests serially in the same process is a
much more likely scenario (that's what FastCGI does); in that case all
we need to do is clean up after each request and it doesn't make much
difference if that state is global or passed down through the functions
that need it.
