# ============================================================
# Do While loops cannot be used on task includes.
# See: https://github.com/ansible/ansible/issues/17098
#
# So as a workaround we use a regular loop to repeatedly attempt
# obtaining a lock.
#
# For this to work we need to skip the subsequent iterations
# once we get a lock, and delay between iterations if we
# did not obtain the lock.
#
# This file encapsulates this logic to reduce the spam from
# skipped tasks in the ansible log.
