One year ago, I started a patch to add Ada task names and thread names.
At the end, the patch for Ada task name went in, but for the thread
names, there were still some work to do e.g. it was unclear how to
properly give the thread name in some cases and/or 
have a consistent presentation of the thread name.

The (partial) patch was giving a behaviour so that we e.g. get:
      [New Thread 0x7ffff701b700 (LWP 13891) "sleepers"]
      [Switching to thread 2 (Thread 0x7ffff781c700 (LWP 13890) "sleepers")]
    instead of:
      [New Thread 0x7ffff701b700 (LWP 13918)]
      [Switching to thread 2 (Thread 0x7ffff781c700 (LWP 13917))]
