This is obviously nonesense! Do you have a piece of code that does
this? In 10 lines? In 100? I doubt it!

It's easy to force Poplog to use a huge amount of heap for testing
purposes:

    false -> popmemlim;
    vars whopper = initv(5e7); ;;; 50 million long words of store

The above two lines will *not* effect the execution of *any*
program! (except that garbage collections may take a few seconds ;)
