Definitely.

Yep, I should be able to do that.  I can even reduce it to a simpler
case of only allowing N connections total.  Saying we only support one
browser session at a time is probably acceptable if it solves the long
https page load times.

Before I go to the effort of hacking up the server to change how/when
it accepts connections[1], I want to try prototyping something like
that Python to make sure that refusing or stalling a "parallel"
connection won't cause the browser to throw up its hands and tell the
user "this page can't be loaded."

[1] We didn't write the server.  We licensed source from somebody
    yonks ago.  It was then abaondoned and maintined by us and by
    applying patches we got from other users in our situation.
