Has anybody else tried sharing swap space between NetBSD and Windoze?

Would it be reasonable to do this by making three partitions (DOS files,
DOS/NetBSD swap, and NetBSD), with the swap one being a regular DOS
filesystem containing only one dedicated swap file, and making a NetBSD
partition referring to just that file's blocks?  How easy is it to find the
start of the Windoze swap file?  Does it contain any metadata at the
beginning?

It would probably be simpler to page to a vnode which was a DOS file, but I
think I've heard rumors about NetBSD writing to DOS partitions being buggy...
how true is this?  For example, is the risk limited to scrambling the "DOS
swap" partition?

Thanks.
