Comment (by jpflori):

 Another important question is to know what the AlgebraicClosure structure
 should cache.
 If its possible not to store all data that was previously cmputed when
 some finite fields aren't used anymore, then it can make sense to discard
 it (imagine working with pseudo-Conway polynomials and only going up and
 up, at some point you won't care about polynomials used for small finite
 fields).
 This is really arguable, but we (or I at least) had several problems
 before (and we still have) because pieces of Sage tend to cache too much.
