I don't understand how it could corrupt the UNDERLYING vfat partition, 
but that is what happend to me twice.  I was unable to mount the USB 
stick as a normal vfat data drive from a regular (non-Live) booted 
system after filling and crashing the persistent overlay when it was 
booted as a Live USB system.  It seems there is a vfat bug that is 
corrupting the filesystem.
