I did a simple test of Mozilla memory usage under Linux by running:
free -mts 3
...and watching the total memory free (phys + swap) as I performed
operations in mozilla. Here are the results (I put memory before event
for formatting purposes):

Close Mozilla
Basically, it looks like Mozilla uses slightly under one meg every time
you open a message, and doesn't give back any memory until you close
Mozilla entirely. Is this by design? (Or are these results meaningless
for some reason?)
