  I didn't use it so I can't tell if it'll suit your needs, but Apple's new   Thread Manager is perhaps the solution to your problem: starting a thread   that issues an SQL resquest then returning to the application to do   something else while the SQL request is processed would be the solution   but I don't know if, at the program level, you are allowed to make   system calls - ask in comp.sys.mac.programmer to the Thread Manager   guru's

  Anyway, if you find a solution you would be very kind to mail it to   me I'm interested...
