Can we make this an unsigned long? We are testing on a system whose
smallest possible configuration is 4GB per socket with 512 sockets.
We would like to be able to specify this as 2GB by default (results
in the least lost memory) and suggest we add a command line option
which overrides this value. We have many installations where 16GB may
be optimal. Large configurations will certainly become more prevalent.

This one needs to match the return above. In our tests, we ended up
with a negative sections_per_block which caused very unexpected results.
