This is just a front-end for calling pminst -l, supplied to make it more obvious what it does.

    $ podgrep -i destructor `modpods`

    Having read L<perltie> you will probably have already guessed that the
    error is caused by the extra copy of the tied object stored in C<$X>.
    If you haven't, then the problem boils down to the fact that the
    B<DB_File> destructor, DESTROY, will not be called until I<all>
    references to the tied object are destroyed. Both the tied variable,
    C<%x>, and C<$X> above hold a reference to the object. The call to
    untie() will destroy the first, but C<$X> still holds a valid
    reference, so the destructor will not get called and the database file
    F<tst.fil> will remain open. The fact that Berkeley DB then reports the
    attempt to open a database that is alreday open via the catch-all
    "Invalid argument" doesn't help.

    Normal object destructor method.
