Summary

• Handle spurious wakeups when waiting for a completion

Summary by cubic

Fixed timed wait in completion to handle spurious wakeups and respect shutdown timeouts. Prevents premature timeouts or hanging during shutdown.

• Bug Fixes
  • Use an absolute deadline and compute remaining timeout each loop.
  • Re-check completion after each wake to ignore spurious wakeups.
  • Enforce a minimum 1 ns timeout when zero is passed.
