Comment (by mabshoff):
But #4639 does not improve this further. Note that "base" is the initial
memory consumption:
{{{
sage: base=get_memory_usage()
sage: M = random_matrix(ZZ,50,50)
sage: for _ in range(100): foo = M.hermite_form()
....:
sage: get_memory_usage()-base
7.5625
sage: for _ in range(100): foo = M.hermite_form()
....:
sage: get_memory_usage()-base
8.515625
sage: for _ in range(100): foo = M.hermite_form()
....:
sage: get_memory_usage()-base
9.5
}}}
Cheers,
Michael
