CLONE - "Locals & Watchers" not being updated while waiting for stack trace

QTCREATORBUG-5474 is reproducible in 3.0:

1. Open simple.pro from Creator's sources.
2. Uncomment line "testEndlessRecursion();" (2921).
3. Build using MinGW.
4. Run in gdb.
   Execution will stop in testEndlessRecursion().
5. Double click the last line in stack trace which reads "More".
   Nothing much will happen, because gdb will be busy for some time.
6. While gdb is busy, double click another line of the stack trace.
   "Locals & Watchers" view won't be updated anymore.
7. Open "Thread" tab and then "Locals & Watchers" view.
   Threads will still be shown.
8. Resize "Locals & Watchers" view.
   This will look ugly, see screenshot.

When Creator can't update "Locals & Watchers" it should at least indicate in some way that it's busy. At the moment, there is not any notification that the displayed values can't be trusted.
