No. "load" will just load table into inactive slot. Following "resume" will implicitly
suspend device and immediately resume with new table (in kernel) so it should be safe.

In devel tree is already "--allow-discard" option for luksOpen/create command.
(But I guess /etc/ctypttab need new option here as well for system devices but
that's must be fixed by initscripts. There will be no cryptsetup command to enable it
on-fly, just for activation commands.)
