We may abort the process of detaching threads with multiple SIGINTs - which are
|
|
|
861f93 |
being sent during a testcase terminating its child GDB.
|
|
|
861f93 |
|
|
|
861f93 |
Some of the threads may not be properly PTRACE_DETACHed which hurts if they
|
|
|
861f93 |
should have been detached with SIGSTOP (as they are accidentally left running
|
|
|
861f93 |
on the debugger termination).
