When considering this, keep in mind that it may be desirable for a  
slave to run builds for different masters run by different teams. I  
have a slave running a few builders for Allmydata on my amd64 box at  
home. I'd like to contribute cycles on that box to other open source  
projects as well, but I really don't want more than one or two  
builders running at once.

In chatting with Brian about this quite a while ago, he seemed to  
think that running a single slave process that polled multiple masters  
looking for work would be the easiest way to to implement this.

However, doing coordination in some way between multiple slaves on a  
single box would meet my requirements. Just don't assume that  
coordination between masters to achieve this is possible.
