Well, you won't be _using_ 70 MBytes, except whilst running P-1 stage
2 on a large exponent, or possibly if running ECM. What George is
talking about is the memory used during "normal" LL testing (or
double checking); the memory usage during P-1 stage 1 is similar,
whilst that required during trial factoring is minimal.
FYI I ran P-1 stage 2 on an exponent around 40 million on a 128 MByte
system running Windows 2000 Professional with Prime95 memory set to
96 MBytes. I would not reccomend this setup; there was some paging
evident, even with no other active applications. You _might_ get away
with 96/128 on a lightly loaded system with a less greedy OS.
