The duration of time for which each application locks each shared resource is critically important in composing multiple independently-developed applications upon a shared \"Open\" platform. The concept of Resource Hold Time (RHT) - the largest length of time that may elapse between the instant that an application system locks a resource and the instant that it subsequently releases the resource - is formally defined and studied in this paper. An algorithm is presented for computing resource hold times for every resource in an application that is scheduled using earliest deadline first scheduling; with resource access arbitrated using the stack resource policy.
