Max smart server connections?

[Maritza Mendez]

Thanks Andrew and thanks Robert!

I was hoping for this.  Branch locks are obviously necessary (thankfully!)
and the fact that the smart server spawn threads means it will work for us.
We are stuck using Windows (coding for dollars) so inetd is not an option
for us.  We have it running as a Windows service and will do a little stress
testing.  If we get any spectacularly interesting results I will share
them.  I expect bzr will "just work" as usual, which is what we love about
it.
