I _think_ we changed from using -O to -O2 between 1.3.3 and 1.4. The
extra optimisation could well slow things down and chew up more memory.

The counters for the number of resident memory pages for these processes
are not getting updated correctly. Essentially, these three processes
don't use any user memory.
