On larger systems with software that has been developed over decades by a
cast of many programmers in everything from
SPL/Fortran/Cobol/Cognos/Speedware/ODBC deadlocks occasionally occur.
Rebooting the system is a major problem, and back tracking the events to fix
the problem is very time consuming. This usually is viewed by the users as a
reason for dumping this 'legacy' system and going with /something new/.

So the big deal is that they (HP) has finally fixed one of the original bugs
in Image (Any programmer that can give MR to a program could deadlock the
database). And the bigger deal is that they made the switch happen
automatically.
