Description:
------------
When using the Prefork MPM, persistent MySQLi connections (for example, but not limited to MySQLi) are reused.
When using other MPMs, they are not. For traced it to:

ext/mysqli/mysqli_nonapi.c: 166

The EG(persistent_list) macro always returns a new list. This results in reaching the MySQL server's connection limit (default at 151) with having all of them waiting in sleep.
