I take it from the numbers you show that you want to allow opening a
new connection to the overloaded server to take a lot longer than
normal. Is it really the case that you need to give it such a long time
just to accept the new incoming connection, or do you really need an
overall long timeout for the call?

As I expect you know, you can have a per thread call timeout:

But, as you say, the overriding connect timeout does not have a per-
thread version. It would not be especially hard to add a per-thread
version of the connect timeout, but it is not something that is
currently available.
