Subject: systemc: When a thread completes, yield to the scheduler.
X-Git-Tag: v19.0.0.0~1727

systemc: When a thread completes, yield to the scheduler.

Don't just fall off the end of the fiber and return to gem5. By
calling yield, we ensure that remaining Processes are run and that
bookkeeping is maintained correctly.
