If the caller is blocked by a currently executing job, this method will return
an IJobStatus
indicating the job that is currently blocking
the caller. If this blocking job is not known, this method will return a plain
informational IStatus
object.

- an optional status object whose message describes the
reason why this operation is blocked, or null
