cannot kill xcdroast

[Alberto Maurizi <alberto@sif.it>]

	I have a problem with xcdroast. It runs into problems
	when mounting a disk partition for writing the cd image.
	From that moment I cannot umount that partition ("umount
	/dev/sda3" hangs the terminal (no Ctrl-C, no Ctrl-Z ...)),
	and it's impossible to kill xcdroast (with kill -9).
	Any idea? Any solution?
