[Swift-devel] provider.staging.pin.swiftfiles feature

[Justin M Wozniak]

Some notes about this are at:

http://www.ci.uchicago.edu/wiki/bin/view/SWFT/CoastersPinned

I should move this to the new site and bring it into the guide if it is 
still useful.

The point of this is to avoid recopying small Swift system files into 
local storage for each job.  If you set that property and use Coasters 
with provider staging, it should just work.

The example on that page shows that _swiftwrap.staging is copied into 
local (RAM?) disk and "pinned"- worker.pl remembers that it is there and 
does not transfer it again.
