<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Flush eventlog buffers from flushEventLog
As noted in #18043, flushTrace failed flush anything beyond the writer.
This means that a significant amount of data sitting in capability-local
event buffers may never get flushed, despite the users' pleads for us to
flush.
Fix this by making flushEventLog flush all of the event buffers before
flushing the writer.
Fixes #18043.
