Send in time has does not guarantee when a message will be sent. It’s ASAP after the event time. If there is a pending message that should be handled before the message you sent then it will be handled and then you will run out of time because you are only waiting 0. If you need to guarantee that you are waiting until the message is sent then do something like:

local sHandled

on Foo
    put false into sHandled
    send “Bar” to me in 0
    wait until sHandled with messages
    — do something else
end Foo

on Bar
   put true into sHandled
end Bar
