Dear hackers
Can somebody shed a light on the two ports ? At first sight, they seem very
similar. Are there plans to update them ? They both are based on a snapshot
dated April 30th, 2001.
Any hints are appreciated.

Hi,
As a part of a little project studying the perfomance of different
malloc(3) implementations I need to gather certain VM statistics.
The problem is that the required data are only available globally, and I
