Peak memory usage could be measured by `ccall` to `getrusage`, right ? I’m obtaining the value of `0 KB` when calling

```julia
run_mtest("create_strings", () -> mtest_create_strings())

```

from the example [here](https://github.com/JuliaLang/julia/blob/master/test/netload/memtest.jl). Should it return a different value ?
