Max Size of Array when using Numeric.py

[Patrick Tufts]

I've created 6000 x 26000 arrays using Python 1.5.2 on solaris 2.6 x86,
and then done various matrix operations on them successfully.

In my limited working with float arrays, Pickle and cPickle have
problems dumping them to disk.  Otherwise, I've had no trouble.
