-// This file defines a simple object which can be used to let the user know what
-// is going on when a slow operation is happening, and gives them the ability to
-// cancel it.  Potentially slow operations can stack allocate one of these
-// objects, and periodically call the "progress" method to update the progress
-// bar.  If the operation takes more than 1 second to complete, the progress bar
-// is automatically shown and updated.  As such, the slow operation should not
-// print stuff to the screen, and should not be confused if an extra line
-// appears on the screen (ie, the cursor should be at the start of the line).
-//
-// If the user presses CTRL-C during the operation, the next invocation of the
-// progress method return true indicating that the operation was cancelled.
-//
-// Because SlowOperationInformers fiddle around with signals, they cannot be
-// nested, and interact poorly with threads.  The SIGALRM handler is set back to
-// SIGDFL, but the SIGINT signal handler is restored when the
-// SlowOperationInformer is destroyed.
