In terms of semantics, I am not sure if at this point timing out is the
correct behavior either in this situation. But I can see that as a
possible approach for sure. I think some of it goes to where you want to
put the fault tolerance for excessive delayed response times.

I guess it is true that excessive load might be the only case when we need
longer timeouts. I guess otherwise clients can also use async response as
a way for longer response times or variable response times from individual

My concern was largely that with slightly complex workflows I might start
seeing this even with lesser concurrent clients but I can probably
experiment to find out if this is true. And I can probably tweak the value
in code directly for when I am doing experiments with larger number of
clients for now.
