Comment (by nbruin):
Just a little note. In [http://trac.sagemath.org/ticket/10963#comment:261]
it was noted that base categories are referenced strongly by a global
cache, and hence are prone to cause "memory leaks". This was rebutted
there by noting that the number of categories created is uniformly
bounded, so the memory use is manageable. This is clearly not true for
these parametrized "categories with fixed base".
The work on this ticket will improve the situation, because categories
parametrized by elements from an infinite set will be less often created,
but it's worthwhile to try and think of what to do if they do get created.
Perhaps we should really try and avoid them completely? Certainly the
infrastructure requirements to support them is radically different,
because such parametrized categories need to be deallocatable (I'm
impressed that Firefox's spell checker accepts that word and not Firefox).
