[rancid] Parrallel Execution of Rancid

Hi All,

I've been searching around for an answer to this and can't seem to find 

My organisation currently has a large number of sites with a varying number 
of network devices each of which we would like to back up with rancid.  Im 
using dotwaffle's patched version to include git support, though this 
shouldn't make a difference for this issue.

Because I am sorting by SITE I have over 1000 rancid groups. Some have only 
5 networking devices, whilst others will have tens of networking devices.

My problem is that the rancid-run is taking a massive amount of time (in 
the order of days).  I have tried playing around with the PAR_COUNT to 
increase concurrency and also reduce the MAX_ROUNDS to reduce the amount of 
time spent on each device.  It looks to me that the PAR_COUNT only comes in 
during the execution of the control_rancid script, which means concurrency 
only hits in within the GROUP.

I'd like a way to run rancid_run on the groups in parallel.  Am I missing 
something obvious here?  Does anyone have any ideas on how to achieve this?

Kind Regards
