I have found in the past (with a non-performer app even) that
one must switch to -64 (and hence the lib64 libraries) when you
surpass the 1 gig limit. At least when shared memory is involved.
I noticed no problems recompiling with -64 and 64 bit libs.
It would seem that 32-bit pointers could access 4G of data (2^32),
but perhaps there is some overhead or other intricacies involved.
