Indeed, and I really don't think it will ever be possible due to
the fact that we're using memory pools for various data types
(eg: a buffer). Adding support for multiple buffer sizes would
make memory management more complex, less robust, and will cause
an important waste of memory.

It's not dirty at all in my opinion, and it even allows you to play
with this tuning without affecting the other customers. You should
remind your customer the two following important points :
- having large cookies means that his site will be extremely slow
for many customers who have to upload the large cookie with
*every request* for *every object* ;
- some visitors will never be able to properly access the site,
either due to browser limitations or to enterprise infrastructure
limitations.
