Lower CPU load when --max-download-limit is used.
There is up and down in speed indicator when enabling
http-pipelining but a download goes well. I think the problem is
that
because http-pipelining is enabled, DownloadCommand is created
for

is
called. In PeerStat::downloadStart(), speed calculation object
is
reseted, which makes download speed zero.
