You might try a commercial product from EasySoft (www.easysoft.com) or OpenLink (www.openlinksw.com). They may have multi-threaded access built in.
(Note, I do not represent either company, rather I just have used their products to test DBD::ODBC on Linux). I haven't tried multiple user access, though.
