Hi,

We are about to start the ruby3.1 transition in unstable. While trying to
rebuild ruby-celluloid with ruby3.1 enabled, the build failed.

Relevant part of the build log (hopefully):

>                Kernel.send(:timeout, timeout_interval) do

The full build log is available from:
https://people.debian.org/~terceiro/ruby3.1/17/ruby-celluloid/ruby-celluloid_0.17.3-1+rebuild1663007422_amd64-2022-09-12T18:30:22Z.build

To reproduce this, you need ruby-all-dev >= 1:3.0+2.  Depending on when you
read this, this might mean installing ruby-all-dev from experimental, or ir the
transition has alraedy started in unstable, a normal build on unstable should
do it.  If you fail to reproduce, please provide a build log and diff it with
mine so that we can identify if something relevant changed in the meantime.
