Mmm, yes, but we need to make *sure* we don't re-use the port and
that it gets dropped at some point not too far, otherwise the
server will stay stuck trying to reply. Managing to make the port
a dead name seems a good way to me. Something like adding a send
right to the port, then dropping the receive right. And making the
__mig_dealloc_reply_port detect that case (if dropping the receive right
returns KERN_INVALID_VALUE, it means it has indeed become a dead
name for a send right, which one can drop instead).

Again, in such code I don't think I can see the whole picture so it's
testsuites that will find out the various cases.
