With just a few tweakings to the texture fetcher (and in particular
a setting that permits up to 32 concurrent HTTP fetches),

Caution... once we begin supporting persistent connections and pipelined requests on the server side (we're working on it), opening that many connections will very likely be considered abuse of the service. Allowing a single server to have that many potentially long-lived connections to the same server would starve the file descriptor pool very quickly at the server end, adversely affecting other users.

HTTP itself recommends that clients not maintain more than 2 connections to the same service [1]. I don't know exactly what limit we will decide is reasonable (I expect that 2 will be ok, but don't know whether or not some larger number will be also).

Please bear this in mind as you think about your designs. I will keep you all informed as things develop.
