Good point. I think I'll prepare a patch, then, that adds to both 
eeschema and pcbnew an option in the preferences dialog: "Maximum number 
of undo items", which defaults to 50 and can be set to any positive 
integer. Up to you and Wayne, of course, whether you'd rather hold onto 
it until after the stable release (I'm fine with that), but I would 
definitely like to see this changed in the near future.
