wp_trash_postがメモリリークしています

投稿IDに基づいて投稿のリストを削除するプラグインがあります。

コードはとても単純です

    foreach ( $post_ids as $post_id ) {
            wp_trash_post( $post_id, true );
        }
    }

しかし、私は約200の投稿を削除した後にWordPressがメモリ不足になっていたことがわかりました。そのため、関数呼び出しの直前にデバッグステートメントを追加しました。

    foreach ( $post_ids as $post_id ) {
            error_log(number_format(memory_get_usage()));
            wp_trash_post( $post_id, true );
        }
    }

メモリ使用量を印刷した後、関数を呼び出すたびに、メモリ使用量が1MB増加することがわかりました。有効にした後のerror_logです。
