[New-bugs-announce] [issue30513] getrusage returns platform-dependent value

[sam-s]

New submission from sam-s:

`resource.getrusage(resource.RUSAGE_SELF).ru_maxrss` returns the peak memory usage, in *bytes* on BSD (including Mac OS X) and in *kilobytes* on Linux.

This means that to get a cross-platform value, the user has to check `sys.platform`, which is fairly inconvenient.

It would seem like a good idea to return a platform-independent value (e.g., multiply the Linux return value by 1000 - or is it 1024?!)
