Just to clarify the event case... our server is not free-threaded.  Once we
are in a request, we are threadbound.  The following request on that same
worker is likely to jump threads, and it's fine, my brief testing today
to confirm, but I presented the patch to the followers of PR 59333 for
review and testing.

This will likely change in 3.0 (no, we aren't going to make requests
free-threaded without bumping the version major - that's too drastic
a behavior change.)  Once a *request* is jumping from thread to
thread, as opposed to the underlying connection, we are going to
have to rethink how the scoreboard presents that information and
how it is refreshed.
