I have now tried this file in a session that has been running for 10
days, and I see no problems with this file.

I'm afraid this is something specific to your configuration, so you
will have to find which parts of your configuration cause this issue.
Also, you originally talked about Emacs getting stuck, while now you
seem to say about slow editing -- is this really the same problem, and
if so, does it get stuck or just works slowly?

In any case, without additional information I don't see how we could
move further in debugging this problem.  I'd begin with looking into
the minor modes you have enabled in that buffer, disabling them one by
one, until the problem goes way.  If that doesn't help, look at
features that hook into post-command-hook.
