Another alternative is leasing the lock so the acquirer has to be alive in
order to keep renewing the lease to keep the lock.

Anyway though, even if there's some mechanism such that HAL can be 100%
sure that an application has hung, will it always be able to release the
lock without the application first being killed? In that case, again, I
think dealing with hanging apps is out of HALs scope.
