A method of managing nested monitor locks in a computer program is provided for an application having at least a first thread and a second thread wherein a non-synchronized procedure is processed by the application. The first thread executes an outer software module while the second thread executes an inner software module. A processing state of the second thread code is preserved before the second thread is configured to release an outer monitor of the outer software module. The first thread acquires the outer monitor of the outer software module so that actions may be completed. Upon completion of actions by the first thread, the outer monitor of the outer software module is released. The processing state of the second thread is restored, such that, actions of the second thread are allowed to be completed.
