By default, tmpfs sets the filesystem size limit to half of the
available RAM. So unless the the processes in the cgroup also consume a
lot of memory besides those for tmpfs, tmpfs write error due to lack of
space will happen first before OOM.

Well, then it should work.
( I do run build bots for Gentoo and fuzzers at this system. So my main
goal is to ensure that neither a build bot nor a fuzzer is harming all
others. )

Thx you for the clarification.
