Zu suspend:
Zitat von
msdn:
This function is primarily designed for use by debuggers. It is not intended to be used for thread synchronization. Calling SuspendThread on a thread that owns a synchronization object, such as a
mutex or critical section, can lead to a deadlock if the calling thread tries to obtain a synchronization object owned by a suspended thread. To avoid this situation, a thread within an application that is not a debugger should signal the other thread to suspend itself. The target thread must be designed to watch for this signal and respond appropriately.
Du machst zwar das supend innerhalb deines Threads. Insofern könnte das sogar ok sein, aber ich würde trotzdem die Finger davon lassen.
