to exceed 10 megabytes in size (especially in X), bump the max
column width from 4 bytes to 5. This will make the ps auxw output
uniform again when a process's rss exceeds 10 megs.
It should be noted that when 5 digits becomes to small, other
solutions should be explored such as displaying them in megabytes
or having ps automatically re-size column widths.
