By the way, I have a new computer which routinely gives me failures (for
several Sage versions) on singular/polynomial.pyx:
sage -t --long --warn-long 56.2 src/sage/libs/singular/polynomial.pyx
**********************************************************************
File "src/sage/libs/singular/polynomial.pyx", line 184, in
sage.libs.singular.polynomial.singular_polynomial_call
Failed example:
for i in range(30): # long time
n = leak(10000)
print("Leaked {} bytes".format(n))
if n == 0:
zeros += 1
if zeros >= 6:
break
else:
zeros = 0
Expected:
Leaked...

Worth opening a ticket or not?
