. o O { I guess chickadee might have been OK anyway, along with e.g.
antique low-end SGI MIPS gear etc of "workstation"/"desktop" form that
any collector is likely to have still running, because they only had
one CPU (unlike their Vogon-spaceship-sized siblings). As long as
they had 64 bit load/store instructions, those couldn't be 'divided'
by an interrupt, so scheduler switches shouldn't be able to tear them,
AFAIK? }
