+\begin{abstract}
+In real-time systems with threads, resource locking and 
+priority sched\-uling, one faces the problem of Priority
+Inversion. This problem can make the behaviour of threads
+unpredictable and the resulting bugs can be hard to find.  The
+Priority Inheritance Protocol is one solution implemented in many
+systems for solving this problem, but the correctness of this solution
+has never been formally verified in a theorem prover. As already
+pointed out in the literature, the original informal investigation of
+the Property Inheritance Protocol presents a correctness ``proof'' for
+an \emph{incorrect} algorithm. In this paper we fix the problem of
+this proof by making all notions precise and implementing a variant of
+a solution proposed earlier. Our formalisation in Isabelle/HOL
+uncovers facts not mentioned in the literature, but also shows how to
+efficiently implement this protocol. Earlier correct implementations
+were criticised as too inefficient. Our formalisation is based on
+Paulson's inductive approach to verifying protocols.\medskip
