so simply don't receive the messages you don't need right now. as i said, 
`receive()` doesn't look to top message only, it scans the whole mailbox, 
trying to find a message that matches. you can use `receiveTimeout()` to 
do nothing if there are no suitable messages. you can also adjust mailbox 
size and mode.
