Description
Was recently pointed out in #903 (comment) that httplib2.Http objects are not threadsafe.
@mwitkow-io suggested that using urllib3 connection pooling would be useful to them.
Other users may also want to use Twisted for their transport layer (instead of httplib2).
Currently (as of 9491053) this is possible in datastore because Connection takes a standalone http object (of any type the user pleases) and the only place the http object is used has a very clear signature
