Subject: [PATCH] SH-4371 Reduce 22mS inter-conenction latency on HTTP
operations. Simple change dropped this value by 7-10mS or so. Any time we
complete an operation on a transport pass, arrange to skip the run-loop sleep
so that we fill a possible empty slot as quickly as possible. With
pipelining, this kind of thing should become unnecessary but for now, we'll
do this to increase throughput.
