Yes, thank you. I had considered this myself in a later message in the
There is still a problem with that (albeit a small one): if tracing the
system with dbg, the traced processes get spurious 'timeout' messages
directly, regardless of any proxies trying to protect them. In this case,
it's easy to match and discard them, and they are only there in debug mode,
but there may be other cases that affect runtime performance.
