Please no.

It feels completely broken. It will not track memory allocated by
external libraries, it adds global state, it makes all allocations more
complex, it does not take the overhead of allocations into account, etc.

Linux has setrlimit(), I am quite sure other OSes have similar features.
Let applications use them.
