Understandable.

This I still don't understand.  The implication is that the only way to
get 64-bit arrays on 64-bit platforms is to install your own mono, and
not use any prebuilt RPMs (as -- presumably -- the prebuilt RPMs would
use the default array size of 32bits).

Why would we want to do this?  Do 64-bit arrays have a performance cost
that would show up in real apps (and not just benchmarks)?

Thanks,
