No they don't! I'm surprised. There is apparently yet something else
that keeps these objects alive. I've tried
import gc
#cm = sage.structure.element.get_coercion_model()
alg='default'
n,m=10,22
B=20
M=sage.misc.getusage.linux_memory_usage()
for j in range(3001):
_=matrix(QQ,n,m,[randint(-B,B)/randint(1,B) for i in
range(n*m)]).echelon_form(alg)
if (j%500) ==0 :
#cm.reset_cache()
gc.collect()
Mn=sage.misc.getusage.linux_memory_usage()
print Mn-M
M=Mn
(clearing the coercion cache has no effect)
