IgnoreExceptionsOfOthers is like IgnoreException but acts on all threads that aren't in the input list. The affected threads are resumed.
ContinueOthers is like ContinueAll but acts on all threads that aren't in the input list. The affected threads are resumed.


Only one of of Resume and IgnoreOtherThreadsExceptions can be set at a time.
Only one of of HandleException and EnableExceptionEvent can be set at a time.


If the input number of threads is 0, this means "all threads".
If the input number of threads is 0, this means "all threads".
