Detailed revision comments: r6130 | marko | 2009-11-02 11:42:56 +0200 (Mon, 02 Nov 2009) | 9 lines branches/zip: Free all resources at shutdown. Set pointers to NULL, so that Valgrind will not complain about freed data structures that are reachable via pointers. This addresses Bug #45992 and Bug #46656. This patch is mostly based on changes copied from branches/embedded-1.0, mainly c5432, c3439, c3134, c2994, c2978, but also some other code was copied. Some added cleanup code is specific to MySQL/InnoDB. rb://199 approved by Sunny Bains
