Hi Richard,

The '--jobs' option for the repo tool parallelizes fetch w.r.t 
manifest.xml.
For example, if there are 8 projects listed in a manifest.xml then 
passing-j4
will run 4 parallel jobs fetching 4 projects simultaneously at a time.
So it is related to whole manifest being operated upon by the repo tool.
