That's what flyspell's "accept for buffer" feature is for.

AFAICT flyspell throws away all words accepted for the session _and_ the
buffer when you switch buffers.  Hence Peter's solution is certainly not
a regression.  Making the feature optional means you still can choose
only between accepting a word for all buffers sharing the same process
or throw away any words you accepted previously and did not add to the
personal word list.

I solved the problem by using a hash table for every buffer I
spell-check and keep all the words there (together with the
corresponding language identifiers and whether they are buffer- or
session-local).
