i used to use ratpoison on a slow netbook with an even slower ssd
drive and found that under a high system load, spawning out to the
rpws shell script to switch between workspaces often was unbearably
slow.
to remedy that, i integrated virtual workspaces into the source so
that switching workspaces was much quicker. i've been running this
for quite a long time and figured i'd send it out in case anyone
wants to formally integrate it or at least run it locally.
it adds a "virtuals" config option which specifies how many
workspaces there are (defaults to 5), a "vinit" command to
initialize those workspaces, a "vselect" command to switch to a
given workspace, and "vdump" command to print out the
workspace/frame config for each one. it basically runs the same
commands that rpws did and uses groups, just does so internally.
