Re: ps output
Thanks Felix. That cleared it up for me.

:
: A "page" in this context is a small part of memory. (Think of "page fault"
: which means
: that an application accesses parts of memory that belong to other apps)
:
: This means that the code and data of the application is swapped to disk.
: When the program is not currently used, its code and data are "swapped"
: (written on disk in the swap-parition), so that the memory can be used by
: another
: application.
: For example, I think I heard that the sun java vm + apps require ~100MB,
but
: most of it is
: swapped, so it only about 10MB (depending on apps) are used.
