Description:
Release build of 5.0.20, based on ChangeSet
  1.2117 06/03/31 11:48:08 lars@mysql.com +1 -0
  BUG#18116: Changed of how mutex is handled for XA and rotating binlog

This effect has not been observed in 5.0.19
(built on the same external machine, same OS version).

On OpenBSD, several tests fail with error 2006 - typical symptom is like this:

=====
ctype_cp932                    [ fail ]

Errors are (from PATH/mysqltest-time) :
mysqltest: At line NNN: query 'INSERT INTO t1 VALUES
(0xF040),(0xF041),(0xF042),(0xF043),(0xF044),(0xF045),(0xF046),(0xF047),
.....
(0xF9F8),(0xF9F9),(0xF9FA),(0xF9FB),(0xF9FC)' failed: 2006: MySQL server has gone away
(the last lines may be the most important ones)
Result from queries before failure can be found in r/ctype_cp932.log
=====

Affected tests:
ctype_cp932 ctype_eucjpms ctype_tis620 gis myisam mysqldump type_enum

How to repeat:
Test suite effect.
