asterisk users - Oct 2005 - Persistant connection for MYSQL command

When doing mysql commands, such as:

exten => _X.,1,MYSQL(Connect connid localhost dbuser dbpass dbname)
exten => _X.,2,MYSQL(Query resultid ${connid} SELECT\ scriptname\ from\ 
mac2pin\ where\ userid=${CALLERIDNAME})
exten => _X.,3,MYSQL(Fetch fetchid ${resultid} AGIScript)
exten => _X.,4,GotoIf($[${AGIScript} = NULL]?5:7)
exten => _X.,5,AGI(${DefaultAGIScript},${EXTEN})
exten => _X.,6,Goto(_X.,8)
exten => _X.,7,AGI(${AGIScript},${EXTEN})
exten => _X.,8,MYSQL(Clear ${resultid})
exten => _X.,9,MYSQL(Disconnect ${connid})
exten => _X.,10,Hangup

over and over again, is there any way to cache the connection so we can 
reuse it, to save overhead?
