With the consequence that all "session-local" words are lost.

ispell-multi.el seems to be able to retain "session-local" words for the
original buffer.  If they are present (or introduced) it should probably
start a new process for the second buffer.

A different problem occurs when you check one and the same buffer with
multiple processes: In this case "session-local" words should be shared
by all processes checking this buffer.  Otherwise, an abbreviation would
be marked erroneous by the French process and not marked by the Italian
one.  As I mentioned earlier, it's much simpler to have Emacs maintain
these words in buffer-local hash-lists and have Emacs override the
results reported by the spell processes.
