And the directory tag values as well?

Oh right. I knew I must have missed something hidden deep in there :] It's probably not catastrophic for most images but I guess it does justify the use of memory mapped files.

Running out of address space continues to be an issue on 64-bit systems. because a system runs a 64-bit OS does not mean that the system is  Just equipped for extra capacity.

True, there can still be arbitrary limits which are low. I guess I'm being too optimistic when it comes to operating systems making good use of hardware. I should know better given that this thread started with the good old 1024 handle limit.
