1. A computer-implemented thread management system, comprising: a calling thread of multiple executing threads, the calling thread having a synchronization context from which an asynchronous callback is requested; an asynchronous library configured to track the requested asynchronous callback as being made from the calling thread and assigned to a thread from a thread pool, the asynchronous library includes a library representation of the synchronization context to capture the synchronization context, call an asynchronous function, pass a restore function to the asynchronous function that includes the synchronization context, process the asynchronous function to restore the synchronization context of the calling thread before execution of the asynchronous callback to the calling thread, and to ensure that the callback executes via the same synchronization context as the original asynchronous request; and a microprocessor configured to execute computer-executable instructions associated with at least one of the calling thread or the asynchronous library.
