O.K. - I'll analyze it here for you:
014e3000-014e7000 r-xp 00000000 03:0a 132241
/usr/local/lib/ggi/default/linear_32.so
014e7000-014f3000 ---p 00004000 03:0a 132241
/usr/local/lib/ggi/default/linear_32.so
014f3000-014f7000 rwxp 00000000 03:0a 132241
/usr/local/lib/ggi/default/linear_32.so
These are the segments that make up the linear32 rendering lib. As you can
see, they extend from 014e3000 up to 014f7000 total. This yields a RAM usage
for the linear32 lib of 0x14000 Bytes or 80k.

7fff4000-80000000 rwxp ffff5000 00:00 0
Stack: 48k.
So it looks like this:
XGGI itself with its own RAM usage gives about 5154k.
It uses standard libs including the dynamic linker for 1472k total.
LibGGI with all its renderers and stuff uses 920k.
You can pretty much safely assume, that much of the standard library stuff
is shared, as other processes will be using the same stuff. This yields
a total memory footprint for XGGI of about 6M.
> Hence XGGI (and ggi etc) would use about 5MB?
Yeah. About that.
