That's fixed in the just released 3.0 - grab it, as long as it's fresh ;)

Yeah - the Python compliler seems to be pretty memory hungry. I had a 15MB
lexer and gave up after a few minutes with most of the swap memory being
allocated.

That's fixed now, too. Now I'm using compressed lookup tables, which are
uncompressed at runtime - just like Java, where .class files seem to have a
size limit.
