Grumble.  It seems to actually care what madvise() returns.  We don't yet
support it, but it _should_ gracefully continue without that support.

You can hack around this by editing src/sys/kern/[u]vm/[u]vm_mmap.c
(depending on whether you're using -current and UVM, or the Mach VM system).
Find the function sys_madvise() and change:

       return (EOPNOTSUPP);

to:

       return (0);

I've thought several times about doing this directly, as many operating
systems we emulate (SunOS, FreeBSD) expect a working madvise() call.  I'll
finally bite the bullet and fix this in -current.
