Hmm...  I wonder how much would be required to emulate just the
Windows system calls (used by normal applications)?  I.e. the same way
qemu-user emulates the Linux and BSD system calls used by normal apps.

WINE does this, of course, but WINE is much bigger than that - it
replaces all the Windows userspace libraries.  That's much bigger than
just kernel behaviour.  I wonder how big the part needed just for
Windows system calls would be.
