Hi. For some reason the BTS thinks this is only a problem in stable.
The above is my attempt at fixing that.

I'm also tagging the bug as ftbfs because I'm getting build failures
due to failing tests.

Regarding the flakiness itself, I get a failure rate around 20%
on machines with 1 CPU and 30% on machines with 2 CPUs. This is
greater than the reference thresholds given by Paul in one
of the gcr bugs.

I'd like to propose a patch, but the tests which fail are
different every time. On a sample of 200 build tries on
different machines, I get the following failures these many times:

   26 multithread-test
   23 proxy-test
   22 range-test
   22 connection-test
   22 auth-test
    6 server-test
    1 timeout-test
    1 hsts-test

If somebody wants to debug this (maybe Simon?), please contact me
privately, as I can provide a VM.

Thanks.
