I just did a quick-n-dirty measurement which indicates that
ICP_OP_HIT_OBJ is only slightly faster thant HTTP/1.1 persistent
connections. The difference seems to be about one RTT, due to
the ICP query/reply before the HTTP request.

See for a graph.

Given this, and the sentiments of others, I see very little reason to
keep the HIT_OBJ functionality in ICP.
