I missed one. Also try #if 0'ing out the pmap_zero_page_area()
call in vm_page_zero_invalid(), also in vm/vm_page.c.
I'm working on a more permanent fix but it is not trivial enough
to post at the moment. Basically, the problem is that NFS's piecemeal
writes confuse the VM system. The new code that zeros invalid portions
of buffers, that the temporary patch #if 0's out, is stomping on pieces
of the NFS system. The bug is in NFS, though, not the new code.
