I can see that a problem in this script is that every time it calls a new instance of Inkscape. This is a problem. I read about the '--shell' command line option but seams to me that it is not working.
It works in the devel version. However, it only saves you time for starting up and shutting down Inkscape. If each slice is exported for a long time (if I understood you correctly) then this gain will be negligible. Its primary advantage is for exporting many fast and small files in succession.
I agree that overall, it is likely to be faster to export the entire file to bitmap, then slice the bitmap. However, I never tried to slice bitmaps this large either, so I don't know how fast it will be.
