My father had the same problems in some old machines (in the 70's),
where the only thing available (at all) was 2k or RAM. So they had to
split bigger programs in chunks of 2k and serialize the results in
tape (that took minutes to write, and could take hours to find/read).
There were some quirks to make it much faster, though, but I don't
remember the details...

Of course, there's no such thing as a compiler in these cases... ;)
