Dear maintainer:

I tried to build this package in buster but it failed:

This is just how the build ends and not necessarily the relevant part.
For full build logs please see:

https://people.debian.org/~sanvila/build-logs/rpyc/

To reproduce, please try building with sbuild on a single-CPU machine, where
this error seems to happen 100% of the time.

Thanks.
