I've been running this patch on BEST's -stable machines for
over a month now with no detriment. I've commited it into
-stable. The patch fixes the lost file write data VM problem
where modified data pages would sometimes not get committed to
disk and the page would then be freed/reused, causing the write
to be lost.
As more and more programs use mmap(), I consider it critical
that we fix mmap() (and the VM system in general). We seem to
be very close, if not already there in -current!
