I forgot to mention this earlier but for the curious, I
used 240mb here because that is USTKTOP-USTKSIZE in 9vx.

P.S.
Has anyone ran into the SEGMAPSIZE limit on native Plan 9?

The current value of 1984mb was set on Sep 16 1998 and if
I've inferred the heuristic correctly, it was meant to be
USTKTOP-4*USTKSIZE.

(At the time, the top of user VM was 0x80000000).

Using the current USTKTOP would give a size of 3520mb.
