I'm planning on removing the exec from DoExec() and instead just
dispatch to the appropriate function.
I don't plan on any changes to the usage of "arguments" to this new
process, basically I'll just store them somewhere and then the forked
backend can process them.
Is there anything I should keep in mind? I'd like this to eventually
be integrated into the source tree -- any particular reason why we use
exec() when we're just re-invoking the same binary?
p.s. this is so my ssl patch doesn't have to negotiate twice -- very expensive
