Detailed description

This pr declares the dk 9 test as broken because of the possibility of trying to dc a binary that already been terminated (as shown in #4652 (comment)) -- basically the test needs the ability to handle 2 different situations. This pr also removes some unneeded code, reverting #4650.

Test plan

The declaration and removal of code are appropriate.
