Comment (by bonefish):
I don't have an explanation for the behavior, but I would recommend
employing the kernel tracing feature to track this down. There's already
some output prepared in `BMessage::_SendMessage()`, though it might be
helpful to add the reply port/token as well. Then just enabled kernel
tracing for `BMessage` (`BMESSAGE_TRACING`), ideally also for syscalls
(`SYSCALL_TRACING`), and for team events (`TEAM_TRACING`) for good
measure. This should allow following the message trail, with sufficient
additional information to see what's going on. Stack traces in KDL
(particularly for the input server, which is otherwise somewhat
inconvenient to debug) help as well. Obviously you can also add other
`ktrace_printf()`s at strategic points.
