If XZ always uses 50% of available memory then adding more RAM won't
help though. The only safe value would be BB_NUMBER_OF_THREADS=1.
But does it? I wonder if reducing XZ_THREADS will actually reduce the
RAM consumption as well. If the problem was common, it would be
reported a lot more, and yet it's not. So I'd suggest you run
experiments with XZ_THREADS first.

Edwin, Alex,
We have a shiny new hammer called PSI or /proc/pressure (1) and I think
that everyone should use it! ;-)
We should both try your build to see if it helps at this early stage but
3x builds on a 64 GB machine does seem to be too much.
If not, maybe we could make a decision about the % of memory /
XZ_THREADS more dynamically based on
available memory or even by making xz be more aware of limited available
RAM somehow.
