multi-nudge error reports out of order and counts incorrect

_From [bruen...@google.com](https://code.google.com/u/109494838902877177630/) on June 14, 2011 16:02:20_

Running infloop manually and sending it many nudges we see two problems:

1) Later nudge error lists are out of order: Error `#1`, `#3`, `#2`

2) The possible leak count is negative:
