we can see if it's a small distance beyond the end, or way out. This may
give some clues as to whether it is being caused by something coalescing
the transfers in spite of the bounce buffers, or simply because of buffer
corruption. (The BT driver seems to occasionally get hit by from this too,
except that it does not trap the transfer, and the system panics later
with vm_bounce_page_free.) This "event" usually happens to me during a
savecore (on the rare occasion that a kernel coredump is actually taken
after a crash - the lack of kernel core dumps is another problem...).
last time. I should have pulled these in last time as it allows easier
comparison of "where we are at" relative to the current version from
cyclic.com. Since this is in a 4.4BSD style tree layout, the changelogs
dont exactly match the file layout, but it's close enough.

directories to check in looking for port startup scripts. The specific gunge
for apache httpd, gated and pcnfsd in /etc/sysconfig and /etc/netstart is
gone now. Note that pcnfsd's troubles aren't necessarily over (and probably
why NetBSD brought it into their sources) - anyone adding pcnfsd will STILL
have to tweak /etc/sysconfig in order to set the new variable
`weak_mountd_authentication' to YES. The flags to mountd are directly affected
by pcnfsd's requirements for non-root mounts, unfortunately! :-(

Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.
