main_q is not used anywhere in the codebase.
It is created in TaskQueueManager._initialize_processes, bundled with rslt_q
into TaskQueueManger._workers, later unwrapped in StrategyBase but not used.
This queue is closed in TaskQueueManger._cleanup_processes.
Historically, it is passed as a init parameter into WorkerProcess,
introduced in 62d7956, but this behavior is changed in 120b9a7.

Update the profile task callback plugin to include a fix for duplicate named tasks. Added additional features to adjust the number of tasks output and the sort order.
For example:
$ ansible web --list-hosts | head -n1
hosts (7):
ERROR! Unexpected Exception: [Errno 32] Broken pipe
Traceback (most recent call last):
File "/home/lamby/git/private/lamby-ansible2/.venv/bin/ansible", line 114, in <module>
display.display("to see the full traceback, use -vvv")
File "/home/lamby/git/private/lamby-ansible2/.venv/local/lib/python2.7/site-packages/ansible/utils/display.py", line 133, in display
sys.stdout.flush()
IOError: [Errno 32] Broken pipe
Such a pipe target will close up shop early when its seen enough input,
causing ansible to print an ugly traceback.

EC2 inventory scripts reads configuration from an INI file. The `instance_filters` option controls which EC2 instances are retrieved for inventory. Filling this option and running the inventory script with Python 3 crashes with the following error:
```python
Traceback (most recent call last):
File "./contrib/inventory/ec2.py", line 1328, in <module>
Ec2Inventory()
File "./contrib/inventory/ec2.py", line 163, in __init__
self.read_settings()
File "./contrib/inventory/ec2.py", line 393, in read_settings
for instance_filter in config.get('ec2', 'instance_filters', '').split(','):
TypeError: get() takes 3 positional arguments but 4 were given
```
The problem is the last parameter of config.get() call, because `fallback` keyword argument is not specified.
The fix handles epmpty `instance_filers` in case of Python 2&3
