Yes, but I do not like depending on the cache.  It's too fragile.  Once
the new schematic file format is in place, this will no be an issue.
Until then, I prefer to error on the side of caution given the cache
issues we've had in the past.

I didn't realize you were keeping tight control of the library commits.
 I'm fine with these changes being added to 5.0.1.  I would like to keep
the libraries relatively stable during the entire 5 stable series.  For
version 6, you can make whatever changes you see fit.
