Comment(by nbruin):
The following example also exhibits a suspicious, steady growth in memory
use. The only reason I can think of why that would happen is that
references to the created finite field remain lying around somewhere,
preventing deallocation:
{{{
sage: L=prime_range(10^8)
sage: for p in L: k=GF(p)
}}}
If you change it to the creation of a polynomial ring the memory use rises
much faster:
{{{
sage: L=prime_range(10^8)
sage: for p in L: k=GF(p)['t']
}}}
Are "unique" parents simply *never* deallocated?
