Allows you to change perl's internal destruction level
Description
This module allows you to change perl's internal destruction level. The
default value of the destruct level is 0; it means that perl won't bother
destroying all of its internal data structures and lets the OS do the cleanup
for it at exit.
For perls built with debugging support (-DDEBUGGING), an environment variable
PERL_DESTRUCT_LEVEL allows you to control the destruction level. This module
enables you to modify it on non-debugging perls too.
Note that some embedded environments might extend the meaning of the
destruction level for their own purposes: mod_perl does that, for example.
