I have not really a idea how DBI or e.g. DBD::mysql are working but I've taken a short look into the c-code of DBD::mysql and have seen that there is the "MYSQL* mysql_dr_connect" which is called in "int my_login" and 2 places of the XS-Code. Takeing a further look into http://www.apachetutor.org/dev/reslist which lists a mod_dbd-implementation for mysql there is the mod_dbd-function "MYSQL* mysql_acquire(request_rec* r, unsigned int flags)". As already stated I admit that I have no idea how DBI and DBD::mysql are working but wouldn't it be enough to decide on some key ({PoolRequest => Apache2::RequestRec}) found in imp_dbh whether to call "mysql_acquire" or "mysql_dr_connect"?
