> Introduce a Python GDB module, and a couple of commands that helps to find queries and fragment instances that are executing in an impalad at the time the daemon crashes.
> One hopes that folks will keep enhancing the module by adding new and useful GDB commands to aid debugging impalad core dumps.
> The initial patch has these:
> {noformat}
> (gdb) source impala-gdb.py
> (gdb) find-query-ids
