[Linux-aus] contest proposal

[Info]

I use valgrind for C. I do not know if there is an equivalent for other languages.

I also have the code report memory at test points. If there were rules covering methods in other 
languages, you can set the equivalent of a printf of memory at the program test points and exit.

I know you can run programs in a script to measure time but the script cannot look at usage within 
the program execution. I think it is valid to include metrics in the program code testing.
