Subject: Does this code spawn lots of objects?

I have the following code:-

dbh = DBI.connect('*', '*', '*')
smtp = Net::SMTP.start('*')
sql = open( "gw.sql", "r" ).read
sth = dbh.execute( sql )
sth.fetch_hash do |row|
  mail         = MailFactory.new()
  mail.to      = "ben.edwards@ingenta.com"
  mail.from    = "ben.edwards@ingenta.com"
  mail.subject = "file from ingenta"
  mail.text    =  "Here is the file"
  mail.attach( "./" + row["IDENTITYID"] + "_" + month + year + ".csv" );
  smtp.send_message( mail.to_s(), mail.from, mail.to )
end
sth.finish
smtp.finish
dbh.disconnect

This code seems to cause a new object to be created for every
iteration of the iterator.  However is it true that 'mail =
MailFactory.new()' causes the previous Mailfactory object not to have
a reference to it and therefore it can be garbage collected?

Is there a better way of coding the above?
