Hi,
(DISCLAIMER: I guess I'm missing something, I'm not an expert of dbd.)
That seems an interesting problem; mysql_thread_init() needs to be
called on every thread creation in order to initialize per-thread stuff
(TLS), while the apr_dbd_driver_t ABI doesn't provide such ones that
allows developers to init / clean it up as far as I know. Otherwise
apr_dbd_driver_t::init is expected to do the task?
Indeed apr_dbd_mysql.c does the wrong thing in the initializer if the
code I'm supposed to look at is the following one:
(From http://apache.webthing.com/svn/apache/apr/apr_dbd_mysql.c)
---
static void dbd_mysql_init(apr_pool_t *pool)
{
my_init();
/* FIXME: this is a guess; find out what it really does */
apr_pool_cleanup_register(pool, NULL, thread_end, apr_pool_cleanup_null);
}

Please patch the attached file to apr_dbd_mysql.c in order to make it
works with threaded mpm.
The current code works only with prework mpm.
MySQL manual claims that this function (mysql_thread_init()), gets
called by mysql_init():

http://dev.mysql.com/doc/refman/5.0/en/mysql-thread-init.html

What kind of errors are you getting?
