Review Comment:
   >> Hmm, don't you see my latest commit? It doesn't increase ref count when 
exporting.
   >> Or I miss anything?
   > This is making the problem worse for all non-offset buffers (which now get 
an extra refcount) while not changing it for the offset buffer (because, again, 
please see the sequence of events that I keep outlining above...)
   
   I know what you meant, and I guess you don't see committed code but only the 
comment, so there is confusion.
   
   In latest commit, I don't increase ref count when exporting offset buffer. 
For non-offset buffers, of course their refcounts are increased as before.
