We may abort the process of detaching threads with multiple SIGINTs - which are
being sent during a testcase terminating its child GDB.
Some of the threads may not be properly PTRACE_DETACHed which hurts if they
should have been detached with SIGSTOP (as they are accidentally left running
on the debugger termination).
