This isn't a bug, it's a feature...officially, according to AT&T. Look
up 'ulimit' in the book.

Microport made it relatively simple to change:
As root, say 'patch /unix ulpatch 0x7fff'. This will raise the ulimit to
32K 512-byte blocks (I think...maybe it's 32K 1K-byte blocks). In any
case, the largest file on my system is in the 3.5 meg range, so that has
worked well for me.

General question: Is that number signed or unsigned? Can I get away with
0xffff, or will it cause problems?
