	One problem that I ran into and also noticed made it into the
PageSwapper was the system hanging during the upgrade from v4.1 to
v4.2.  This occured after the message about deinstalling images (end
of Phase 1?).  After deinstalling images the upgrade procedure goes
through and deletes a large number of files (performing a lot of file
operations).  If it goes far enough it says something to the effect
"Now working on [SYS0.SYSEXE]" and "Now working on [SYS0.SYSMGR]"
depending on what system directory it is working on.  On one of our
systems, deleting the files would consistantly cause a hang.  The
work around I used was to restore the F11BXQP.EXE from the "REQUIRED."
saveset of the VMS 4.2 kit into sys$system and reboot (after having
to reboot out of the hung upgrade).
	This problem is similar to all the other hang conditions that
have been associated with the early F11BXQP's but it is especially
unnerving when it occurs in a "blind" section of the upgrade.  The
fix only took about 6 passes at the upgrade and about the same number
of hours to understand and finally get going.
