Thanks.  Is there a work around where the lock leakage can be fixed and the 
3ware daemon can work ?  I dont know who (if anyone) has the source code to 
the 3dmd program, is this something that could be easily fixed in it ?  Are 
there any other programs that will break as a result of your commit as well ?
