I've read a bit of the thread.  There seems to be an error involved,
but I didn't see a backtrace for this error.  Can someone produce it?

There's also some conjecture about interference related to
eglot-ensure.  Is it_only_ related to `eglot-ensure`?  How?

This part of Eglot is extremely delicate. I spent many hours making
sure the checks start only when they should, results of previous checks
are properly erased, etc.  This is because the Eglot Flymake backend
doesn't real work like other backends in that it cannot issue an order
to the LSP server (at least in most servers it can't) to provide diagnostics.

So I need to understand the problem and its impact in detail.
