How Pspell/Aspell Dictionaries Work (was Re: Footprint)

[Kevin Atkinson]

When Pspell is used in conjunction with Aspell most all dictionaries are
mmaped in.  This means that when more than one open application use the
same Aspell dictionary the dictionary is only loaded once in memory, this
is not true for Ispell where each process will have its own copy of the
dictionary in memory.  Being mmaped in also means that the dictionary will
automatically be unloaded from memory when it is not being used and the
memory is needed for other things.
