avoid potentially very long bwlimit delay at start 
I first saw this getting with -J2 over ssh, but later saw it also
without the -J2. It was resuming, and the calulated unboundDelay was
many minutes. The first update of the meter jumped to some large value,
because of the resuming, and so it thought the BW was super fast.

Avoid by waiting until the second meter update.

Might be a good idea to also guard for the delay being many seconds
and avoid waiting. But how many? If BW is legitimately super fast, and a
remote happens to read more than a 32kb or so chunk at a time, it could
in theory download megabytes or gigabytes of data before the first meter
update. It would actually be appropriate then to delay for a long time,
if the desired BW was low. Could make up some numbers that are sane now,
but tech may improve.

(BTW, pleased to see bwlimit does work with -J. I had worried that
it might not, if the meter update happened in a different thread than
the downloading, but it's done in the same thread.)
