This requires very large amounts of memory at runtime, it's crashing
for me with various input files with the 4GB datasize limit that is
the default for the 'staff' group (often leaving a just-under 4GB core).
If there's nothing that can be done about the memory usage, is it
worth adding a warning in MESSAGE?
It seems a lot happier with 8GB available.
