[trac420] Try not to timeout on slow machines

Some of our built machines time out, for two possible reasons:
* They have long buffer before they start blocking. Therefore the amount
  of data sent is increased.
* They have clock with low precision, so if now - last_sent > 0.1:
  happens after a long time. So the timeout waiting for that was
  increased.
