This afternoon I fixed mandelgen.py to generate all values as needed, on the fly, so as to minimize the memory requirements. The last bugaboo was where I had:
for index in range(current['height'] * current['width']):
While I knew that range generated a list, somehow I thought it did so in a memory-efficient manner. It doesn't. Switching to a while loop eliminated that last byte-guzzler and I can now run the program on my Tektonic server, which has no swap space and I haven't yet figured out the Debian way of using a swapfile. Debian is great for ease of upgrades, but damn, they do make some things a lot more complicated than other GNU/Linux systems I'm familiar with.
