record size computation


I have computed galoisinit(P324), where P324 is a degree-324
polynomial, using a 64bit gp binary on a 950MHz Solaris machine with
64GB of RAM.   The initial stack was 16GB.  The largest the process
grew in the memory was 8GB.  The size of the output is 500MB.  The
total runtime was 12hours.

All those are huge numbers.  Most people don't have 64GB RAM 64bit
machines at their disposal.  For once, the bottleneck is not a
runtime complexity of algorithm, but hardware limitations due to
the implementation.  

Any comments, Bill? :)
