# This module verifies that AnsibleModule works when cwd does not exist.
# This situation can occur as a race condition when the following conditions are met:
#
# 1) Execute a module which has high startup overhead prior to instantiating AnsibleModule (0.5s is enough in many cases).
# 2) Run the module async as the last task in a playbook using connection=local (a fire-and-forget task).
# 3) Remove the directory containing the playbook immediately after playbook execution ends (playbook in a temp dir).
#
# To ease testing of this race condition the deletion of cwd is handled in this module.
# This avoids race conditions in the test, including timing cwd deletion between AnsiballZ wrapper execution and AnsibleModule instantiation.
# The timing issue with AnsiballZ is due to cwd checking in the wrapper when code coverage is enabled.
