the test environment). `import hypothesis` will cause this number to be decremented,
and the pytest plugin increments at load time, then decrements it just before each test
session starts. However, this leads to a hole in coverage if another pytest plugin
imports hypothesis before our plugin is loaded. HYPOTHESIS_EXTEND_INITIALIZATION may
be set to pre-increment the value on behalf of _hypothesis_pytestplugin, plugging the
hole."""
