Good idea, but there is a downside: the connection pooling here is
closely tied to server operations, not client. (also the client API is
pretty basic right now).

On the other hand, the evthr code (libevhtp/evthr) can be used
independently. It's quite handly once you get the hang of it. It
operates much like what Nir has suggested (finding the least utilized 
pool, etc).
