That is current behavior unless buffers use different languages for
spellchecking or have a set of localwords defined (which may be different
for different buffers, needing process restart).

Doing this without the kill-ispell-on-kill-buffer machinery may still leave
some corner cases. 

Noticed that this dual personal dictionary behavior seems to be an ispell
only feature. If properly handling this is causing more harm than good, it
may even be dropped by forcing ispell-process-directory to always be $HOME.  

Anyway, I have commited a possible fix for jidanni's problem, making
parent-dir 'owner' of ispell process in a minibuffer'. Hope this fixes the
problem.

Closing bug report,
