I'd suggest using the grid of guides script instead, as you can set and clear them on the fly.

Something's broke in 2.6.6, at least the MacOSX build. I am able to run your script and it generates the guides but when I select "snap to guides" the paint brush doesn't snap. Luckily I have VMWare, too bad sourceforge.net seems to be borked right now. ;^o
