I was having many problems with crash-on-exit problems when I was using the OpenThreads::Cancel facility. I found it a lot more stable to just set a global variable and check that periodically within each thread and just exit when it was set. Since I'm on Linux OpenThreads uses pthreads underneath, and I never got a satisfactory explanation on why pthread_cancel would behave that way.
The problems I found were generally down to pthread_cancel only cancelling when the thread gets to a pthread cancellation point, if the code doesn't go through any of these then pthread_cancel will be ignored. If other code then assume that the cancel has succeeded and deletes associated objects the threads can end up reference deleted memory. The are several different types of pthread_cancel you can use. I can't recall all the details off the top of my head, running through man pthreads or online docs will help.
