SD card unpartitioned space -- used for swap?

For about two years now, I've been defining a swap partition on the
(external) "permanent" SD card I use with my XO-1 systems.  So far, I
have never experienced any problems with that setup.

The advantage is to relieve "memory pressure".  In particular, I am a
heavy user of 'yum' - and that swap space (together with judicious
specification for /var/cache/yum) allows me to run HUGE yum installs.


p.s.  By the way, I also had a swap partition on the (external)
"permanent" SD card I had in an XO-1.5.  But unless running an
"unreasonable" number of Activities simultaneously, I do not recall ever
seeing that swap partition on the XO-1.5 being used -- apparently the
larger RAM size on the XO-1.5 rarely gets into "memory pressure".
