Instruments and mach_msg_trap

I think I'm starting to get the hang of Instruments, sort of. Ok so in my previous post I didn't realize what that mach_msg_trap was about. Apparently, it's got something to do with the thread doing nothing (blocked), like waiting for the next frame to start (good) or when allocing and releasing a lot of objects (bad).

Will see if the above still holds after I get more experience playing around with Instruments.

The question is: how to distinguish between both only by looking at the instruments? I'm in the hope my time on mach_msg_trap is about idle time! :)
