When loading updates from the beginning of 3.7alpha, after update #5501 
(recreate special objects array), the updates slow down dramatically.  
Some sort of timeout is occuring on each update, because each update 
takes 20 seconds after this, which can make it take a looong time to get 
up to 5548.

However, this only happens as long as you haven't saved & restarted your 
image.  Once you do this, or if you start with a fresh post-5501 image 
from the ftp site, updates are fast again.  But I just added an update 
to 3.6 to allow people to move to 3.7alpha if desired, so it'd be good 
to fix this.

So, I'm thinking I should retrofit update 5501 (or perhaps 5502) so that 
it prompts the user to save & restart his/her image.  Alternatively, if 
there's a magic do-it which will clean things up so that the restart 
isn't necessary, that would be even better.  (I would then include just 
the do-it with the retrofitted update.)  Is there such a do-it to clean 
up after the special objects array recreation?

p.s. to debug this, I added some extra transcript output messages in the 
update code. here's some of the relevant output:
