/**
* Base class for all PHPUnit Framework exceptions.
*
* Ensures that exceptions thrown during a test run do not leave stray
* references behind.
*
* Every Exception contains a stack trace. Each stack frame contains the 'args'
* of the called function. The function arguments can contain references to
* instantiated objects. The references prevent the objects from being
* destructed (until test results are eventually printed), so memory cannot be
* freed up.
*
* With enabled process isolation, test results are serialized in the child
* process and unserialized in the parent process. The stack trace of Exceptions
* may contain objects that cannot be serialized or unserialized (e.g., PDO
* connections). Unserializing user-space objects from the child process into
* the parent would break the intended encapsulation of process isolation.
