Why? How may primes are there amont the first 2^32-1 numbers?
Shouldn't be unreasonable to just stick it in a table/map if all
you're interested in is getting the fastest result regardless of
algorithm... Seems quite arbitrary that you allow various tricks to
make C# look better (it might still be faster, but I haven't seen you
do a fair comparison yet!), but won't take it to its logical

If you *are* interested in a fair comparison I recommend you don't
cheat in either language, and try to write a more general algorithm
for both, that have the same properties (e.g. lazy streams of primes
in both, or a fixed up-front allocated array of primes in both).
