Multiquery hangs

[cbizon]

Running a multiquery with 37 subqueries. I will see this in strider:

    raise exc from None

    raise mapped_exc(message) from exc
httpx.ReadError

And then the caller never gets all the answers

This is the treats query using about 30 of Kara's rules. I was able to get things to run by reducing to 3-5 at a time (most of the time that would work).

This is mostly fixed, but reliably happens for certain inputs.

With MONDO:0005148 (T2D) strider frequently hangs at 74 the 75 rules for over 1 hour.

I have also witnessed it for MONDO:0005016 though I don't know how many rules got stuck
