You probably don't want to use top for this -- the memory usage that top
displays includes memory that is being used as a disk cache so it will
always look like you're using almost all of your memory.  Use "free"
instead and then check the line labelled "-/+ buffers/cache" for a more
realistic view of how much memory will be available to applications if
they need it.
