If you make multiple copies of the Speller class within the same
application than Aspell 0.60 will use the same dictionary classes for all
of them when the same dictionary is used.

On Unix (and possible on Windows with Cygwin) dictionaries are loaded from
the disk in such a way that different applications that use the same
physical file will use the same read only memory, is a very similar
fashion to how shared libraries are loaded into memory.
