On a slightly related note, I was thinking about this, but more from
the memory-preservation angle, as Linux [the kernel] features
copy-on-write for regular fork.
Then, I realized that the memory wouldn't really be saved, not for
long anyway, because when GC runs, it marks bits on everything.
Is my perception correct?
