Merge rev 1.202 from i386/pmap.c (back in 1998 by John Dyson):
Make flushing dirty pages work correctly on filesystems that
unexpectedly do not complete writes even with sync I/O requests.
This should help the behavior of mmaped files when using
softupdates (and perhaps in other circumstances also.)
