? No.  Trying this example: http://bpaste.net/show/fCUTnR9mDzJ2IEKrQLAR/

...really allocates 4GB of RAM, and on a 4GB machine it causes some
swapping.  It seems to work fine.  I'm not sure to understand you.
I'm also not sure that a property as essential as "disables swapping"
should be omitted from the man page; if so, that would be a real man
page bug.


A bientÃt,

Armin.
