Description

When there are pending event time timers for a window by definition they are within the window so it should not be possible to GC the window nor to shut down the pipeline.

Imported from Jira [BEAM-2791](https://issues.apache.org/jira/browse/BEAM-2791). Original Jira may contain additional context.

Research direction

Start by locating the DirectRunner shutdown path and the event-time timer and window lifecycle code; the issue does not name specific files or tests. Review Jira BEAM-2791 for the missing context, then verify that pending event-time timers prevent window garbage collection and pipeline shutdown.
