I would rather call it (yet) an undocumented feature :-)

Yes, I think your diagnosis is right.  The builder-client sets that
memory limit for each launched process so it could avoid uncontrolled
consumption.   But the original 1-GB limit may be too strict these
days, as the build phase could easily exceed this (legally),
especially on 64-bit architectures.  Probably this should be factored
out to a configuration file or increased to 2 or 4 GB.
