No, only the reader-process is killed and
the scanning-bit is reset so the next sane_read
calls the routine that makes the scanner aborting the
scan.

But in that routine it does not matter if I call a
reposition-scanner or a wait-scanner command, the scsi-command
always hangs while writing the command-bytes to the device!
