[Image-SIG] Workarounds for MemoryErrors

I want to create a very large RGBA image (96000x72000 pixels).
I have 4GB of RAM.
Is there an easy way of getting around this error by having PIL only
allocate one section of the image at a time?
If PIL does not have any internal trick to work with large images then
I'll have to make 4+ smaller images one at a time, but then I'm not sure
how I could combine them without needing to allocate a memory chunk for
the whole image.
Otherwise I suppose I'll have to try with some other language, perhaps
C/SDL, though a quick calculation seems to show that such a large RGBA
image is just unworkable. Is there some way of using disk space rather
than memory? Does not matter if it is slow, just that it is possible!
