+ < youpi> in which error cases a reply port will actually have been consumed
+ by mach_msg ?
+ < youpi> it seems at least MACH_SEND_NOTIFY_IN_PROGRESS do?
+ < braunr>
+ < braunr> "These return codes imply that the message was returned to the
+ caller with a pseudo-receive operation: "
+ < braunr> isn't it what you're looking for ?
+ < youpi> well, it's hard to tell from the name
+ < youpi> I don't know what "pseudo-receiv operation" means
+ < braunr> it's described below
+ < youpi> ew
+ < braunr> it looks close enough to a normal receive to assume it consumes
+ the reply port
+ < youpi> so it's even more complex than what I thought
+ < youpi> well, no, it returns the right
+ < youpi> actually the error I'm getting is MACH_RCV_INVALID_NAME
+ < youpi> which I guess means the sending part succeeded
+ < youpi> the case at stake is proc/mgt.c: S_proc_exception_raise()
+ < youpi> when the proc_exception_raise() forward fails
+ < youpi> currently we always return 0, but if proc_exception_raise()
+ actually managed to send the message, the reply port was consumed and
+ MIG_NO_REPLY should be returned instead
