"""Main module implementation specific for windows.
This module should never import from the multiplatform one (main/__init__.py),
but the other way around. Likewise, this module should *not* have any logic
regarding error processing or decision making about when to send a given
signal.
Also, most of the logging is being made in the main module to avoid
duplication between the different platform implementations.
