- It is not guaranteed that a target reset will work of the drive
is really hung.
- The only bad thing that may happen with bus device reset is that
other CD-writing or tape processes will be interrupted

Of course Stability! The Linux sg driver still misses features that my SunOS
scg driver already implemented in 1986!

Believe me, Linux does not support it! There is a non-functional ioctl()
since some months.... libscg supports it. Once Linux implements reset,
cdrecord (even old versions [if the interface is not changed]) will
support it without intervention.
