sense to bound the number of connections we keep open

But it's not just letting connections linger, url-http has a
mechanism to store open connections in a hash and reusing them:

Does someone here know what the point of this was? Is quick
repeated http connections to the same host:port such a frequent use
case  that it's worth it to keep open http connections in a hash,
instead of closing and disposing them when the request ends?
