Some memory leaks remained in Sage's CPLEX interface, as reported by Geoff
on http://ask.sagemath.org/question/1170/memory-blowup-with-milp
Fixed there, after a lot of debugging `:-P`
You can check the difference by running the following piece of code :
{{{
while True:
p = MixedIntegerLinearProgram(solver = "CPLEX")
get_memory_usage()
}}}
The result is scary.
