SYMPTOMS
You run a program that you built by using the Microsoft .NET Framework 1.1. After your program has been running for a short time, the CPU Usage suddenly increases and a threadpool thread becomes corrupted. When this problem occurs, threads no longer unload.

You experience the following behavior:
 * 1) CPU Usage suddenly increases and one of the threads in the program deadlocks.
 * 2) Another thread continues to create manual events.
 * 3) A wait thread fires repeatedly on an AutoResetEvent that has a Win32 native manual event under it because the wait thread is trying to process the completion.
