Changes between Initial Version and Version 1 of Ticket #42044, comment 4

-                      initial
+                      v1
 Not sure how the status is today, but I can imagine, from the above testing, that it would at least increase the memory usage and the run-time. That might overshadow the positive things it could have ;-)
+ps: I found two files where the [https://phpunit.de/manual/current/en/appendixes.annotations.html#appendixes.annotations.preserveGlobalState preserveGlobalState] annotation is used:
+{{{
+tests/phpunit/tests/oembed/headers.php: * @preserveGlobalState disabled
+tests/phpunit/tests/ajax/Response.php:   * @preserveGlobalState disabled
+}}}
