Fix repeated downloads

Browse Source 
- a bug in RandomTrackingDict caused requesting to download the same objects
  over and over
- the bug is that the lastObject wasn't properly initalised, this caused the
  write buffer to fill with "getdata" requests until the first object was
  received
- this PR should address both the excessive bandwidth as well as excessive CPU
  usage during downloading
