The "VIRT" column is not a reliable number for how much memory that
particular app is actually taking up in RAM.  Much of the memory
referred to there may be shared with other applications that rely on
the same underlying libraries, such as the standard C libraries.  If I
recall correctly, these are "virtual mappings" of memory.

For instance, I just started up Twinkle, a KDE program, on my GNOME
desktop, and the VIRT for that program is around 1371 MB.  (Yes,
that's a lot, but again, it's not all actually loaded in RAM.)
