New submission from Kurt Rose:

The documentation in the resource module for get_page_size() is incorrect.

resource.getpagesize()
Returns the number of bytes in a system page. (This need not be the same as the \
hardware page size.) This function is useful for determining the number of bytes of \
memory a process is using. The third element of the tuple returned by getrusage() \
describes memory usage in pages; multiplying by page size produces number of bytes.

On Linux, the value returned in getrusage().ru_maxrss is in kilobytes.  On OS-X it is \
in bytes.  Ideally, this could be put into the documentation, but at least remove the \
inaccurate recommendation to multiply maxrss by page size :-)
