Patent abstract

A method and system for implementing detecting deadlocks in interop-debugging is described herein. One or more synchronization objects that an application program interface (API) could block on are identified. A canary thread that takes one or more of the synchronization objects is created. The canary thread is called to take the one or more synchronization objects. If the canary thread returns within a predetermined timeout period, then the one or more synchronization objects are available and safe to take. If the canary thread does not return within the predetermined timeout period, then the one or more synchronization objects may not be available.
