swap file

Hi all,

my RTP system is living on limited disk space (500 Mb),
but it keeps a big swap-file. As I learned, RTP does not
do any swapping anyway (except for applications that do
it by themself), so I think keeping a swap-file is pure luxury.

Therefore my question: Is it save to remove it, or is there a
chance to shrink it’s size without ruining the system?
