Abstract
Example embodiments of the present invention provide a method, a system, and a computer program product for managing tasks in a system. The method comprises running a first task on a system, wherein the first task has a first priority of execution time and the execution of which first task locks a resource on the system, and running a second task on the system, wherein the second task has a second priority of execution time earlier than the first priority of execution time of the first task and the execution of which second task requires the resource on the system locked by the first task. The system then may promote the first task having the later first priority of execution time to a new priority of execution time at least as early as the second priority of execution time of the second task and resume execution of the first task having the later first priority of execution time.
