Abstract
A method, apparatus, and computer instructions for executing a handler in a multi-threaded process handling a number of threads in a manner that avoids deadlocks. A value equal to the number of threads executing in the data processing system is set. The value is decremented each time a lock count for a thread within the number of threads is zero. A thread within the number of threads is suspended if the thread requests a lock and has a lock count of zero. A procedure, such as a handler, is executed in response to all of the threads within the number of threads having no locks.
