David Greenman f6b04d2bfb Changes from John Dyson and myself:
Fixed remaining known bugs in the buffer IO and VM system.

vfs_bio.c:
Fixed some race conditions and locking bugs. Improved performance
by removing some (now) unnecessary code and fixing some broken
logic.
Fixed process accounting of # of FS outputs.
Properly handle NFS interrupts (B_EINTR).

(various)
Replaced calls to clrbuf() with calls to an optimized routine
called vfs_bio_clrbuf().

(various FS sync)
Sync out modified vnode_pager backed pages.

ffs_vnops.c:
Do two passes: Sync out file data first, then indirect blocks.

vm_fault.c:
Fixed deadly embrace caused by acquiring locks in the wrong order.

vnode_pager.c:
Changed to use buffer I/O system for writing out modified pages. This
should fix the problem with the modification date previous not getting
updated. Also dramatically simplifies the code. Note that this is
going to change in the future and be implemented via VOP_PUTPAGES().

vm_object.c:
Fixed a pile of bugs related to cleaning (vnode) objects. The performance
of vm_object_page_clean() is terrible when dealing with huge objects,
but this will change when we implement a binary tree to keep the object
pages sorted.

vm_pageout.c:
Fixed broken clustering of pageouts. Fixed race conditions and other
lockup style bugs in the scanning of pages. Improved performance.

This install procedure is ALPHA code, and        `--{__________)
may very possibly *DESTROY* the contents of your
ENTIRE DISK!  Please do not proceed with this installation
unless you've adequately backed up your data first!

If any errors occur during this installation, you can see them
by toggling over to the alternate screen - type ALT-F2 to switch
over, ALT-F1 to switch back to the install screen.  The debugging
output on the second screen may be very valuable to us in understanding
your bug report, so please be sure to take note of it when reporting
any failures in the installation!  Thanks!

Menus and scrolling output windows may be traversed with the arrow
and Page Up/Page Down keys.  To suspend the installation at any point,
hit ESC twice.  Hitting TAB will move the focus to different controls.
If you've ever dealt with a DOS installation, you'll know how to deal
with this.

For a more complete description of what's new in this release, please
see the release notes.

For more documentation on this system, it is recommended that you purchase
the 4.4BSD Document Set from O'Reilly Associates and the USENIX Association.
ISBN 1-56592-082-1  We have no connection with O'Reilly, we're just
satisfied customers!

Have fun, and please let us know of any problems you encounter with
this release!

Comments should be sent to:

Bug reports should be sent using the `send-pr' utility, if you
were able to get the system installed, otherwise to:

Please have patience if your questions are not answered right away -
this is an especially busy time for us, and our volunteer resources
are often strained to the limit (if not somewhat past!).

Thanks!
