First of all I can safely say that we are always annoyed when storables change.  Having said that - we have so few 64-bit storables that I don't think it would be too much of a problem.  For the app that I'm working on (persistent_server), the problem lies in storables that are built on the fly, not stored on disk, so that shouldn't be a problem after a fix.  I still need my 64-bit program to read storables previously written to disk, but these storables are intermediate in nature and will be rebuilt automatically if we delete them.  Again, not a really big problem.

I meant that after fixing this bug of not being able to retrieve 64-bit storable
on 32-bit system, do you expect it to be able to retrieve existing 64-bit
storable or you don't care if it doesn't since you can rebuild those 64-bit
storable?
