Ardour will give this warning for any amount of maximum locked memory. It is
a /warning/, not an error. It points the user to a potential problem which
they should look at if they run into issues.

"This might cause Ardour to run out of memory before your system runs out of
memory... "

The warning means you MIGHT run out of memory BEFORE your whole system runs
really out of memory.
