[gin-jobs] Standarized Execution Environment

[JP Navarro]

Virtualization is one approach for an application to carry it's own
environment to arbitrary computing elements.  It's best suited for
applications that don't need access to other non-Grid CE resources,
like cluster file-systems, local software, and non-IP interconnects
(Myrinet and Infiniband).

Some applications need access to these non-Grid CE resources and
don't want the added overhead of constructing a fully functional
OS image with their application.

I think it's important to support both use cases.  Standard
environment variables are important for the non-virtual use case.

JP Navarro
