Sometimes, it is necessary to cancel a garbage collection operation. When GC is called using the standalone executable, i.e., from a command line, Control-Cing the process does the trick. When calling GC programmatically, though, there is no mechanism to do it. Add checks in the GC process so that a custom cancellable progress monitor could be passed in order to cancel the operation at specific points. In this case, the calling process set the cancel flag in the progress monitor and the GC process will throw an exception that can be caught and handled by the caller accordingly.
