For SANs or iSCSI  this can make some sense- but only if you really 
really trust the release mechanism (which I don't in any heterogeneous 
environment).

The other question to raise is how do you sensibly represent the disks 
to the non-winner node and field failed attempts to operate on the 
shared disk? In other words, how do percolate RESERVATION CONFLICT 
errors up to the application level?
