... of mounted volumes, even for filesystem images mounted via loop device from an USB volume and swap space from USB devices, while the USB subsystem is to be stopped

this should avoid a "hanging system", if the USB host is stopped while important parts of the system are swapped out - in this moment it leads to a "read error" condition from the unavailable swap space
the obvious way to ensure this, is a modification of post_install in the var.tar file

added some "swapoff" calls to /etc/hotplug/storage (and usb.pandu) to restore swapped-out pages prior to stopping the whole USB subsystem or eject a single USB device - the result is the new script "mod_swapoff" available in 0.3.5
