PS is not a rasterised language. It can generate output for any part of the
page at any time in the document. Thus, it can only be "banded" after it has
been rasterised. The 1M or so of RAM is the rasterising buffer ( save for the
font caches). If the PS input could be constrained, your suggestion would
work. However, that would upset the essential essence of what PS is all
about.
