On Win32, something like 3GB. Maybe a little more on Linux32, but
there's a physical limit at 4GB. 

On Linux 64, the motherboards set the limit in practice, 32GB systems
have been reported working and I think at least 64GB should be
possible. I seem to recall that the maximum _virtual_ memory is not
quite 2^64, but it will be pretty huge (2^48, 256TB)?.
