The ftape utils have a tool called swapout which tries to 'free'
large chunks of memory which then can be allocated by the ftape
module loaded subsequently.
I don't know if this approach does also work with *such* large
chunks like yours.

Wasn't there a problem with a process having mlocked memory in the wrong place and the application hanging? Or the kernel hanging? Or something. Can't remember.
