If a nonpreamtable scope=global SRB does a pause
And another SRB is scheduled does it get dispatched ?
Being non-preemptable means that z/OS won't take control away from the
unit of work without cause. Cause being something like a page fault
requiring a page-in from DASD or a SETLOCK request for a local lock that
is unavailable. Or if you *explicitly* request to give up control by
performing a SUSPEND w/Token or a Pause.
Once the SRB has has lost or given up control the next ready unit of
work will get control based on address space and minor priorities. If
the work required the local lock and it is not available then the work
is 'not ready' until the local lock becomes available.
