This is a bug:

I sometimes wonder whether something basic like "no more than one
compile task at a time" would be sufficient in practice to avoid
overloading all cores.

It would also help with RAM usage, there are some combinations of
recipes where the build gets aborted by the oom killer on my laptop
(8 cores, 32 GB RAM) when bitbake runs the compile tasks in parallel.
