------------------------


Because the SGE DRMAA implementation offers reconnectable sessions, it should be
possible for a job to determine what DRMAA session submitted it.  The most
obvious way to do that would be to expose the DRMAA session id as an environment
variable in the job's environment.

As a follow-up to this feature, it should also be possible to tell
Session.init() to reconnect to the parent job's session without having to know
what that session's id is.
