Perl::destruct::level is an interface allowing one to change perl's internal destruction level. while this functionality is available through the perl_destruct_level environment variable when perl is compiled with debug support, this module provides it for perls without -ddebugging.

the default value of the destruct level is 0; it means that perl won't bother destroying all its internal data structures, but let the os do the cleanup for it at exit.

relevant values recognized by perl are 1 and 2. consult your source code to know exactly what they mean. note that some embedded environments might extend the meaning of the destruction level for their own purposes: mod_perl does that, for example.
