Hi Alain.

>>I conclude by this that only about 2.5MB are available in *total*
So it hit me today, I recall seeing the memory map for the 4MB RAM address =
space (0x0 - 0x3FFFFF), and sure enough, only around 2.5 MB allocated to us=
er processes:

KERNEL ONLY =3D 00_00_00 =E2=80=93 07_FF_FF (512 KB)
User Process =3D 08_00_00 =E2=80=93 2F_FF_FF (2.5 MB)
Shared Lib =3D 30_00_00 =E2=80=93 37_FF_FF (512 KB)
Kernel VM =3D 38_00_00 =E2=80=93 3F_FF_FF (512 KB)

So I don't think increasing swap is going to help much given the limited ad=
dress space.
