[pLog-svn] memory usage / metrics

[Jon Daley]

 	I was just playing around with that large database installation, 
and discovered that the metrics are not correctly reporting the memory 
usage...

 	What is written to the file is the amount of memory currently 
being used by the php script, not the peak amount that was ever used 
during this script's execution.

 	get_peak_memory_usage() would be better, but apparently it is not 
available yet.
