I might well let the OS clean up such things on process termination, which is
fine (assuming it does so), since these are all OS objects. Is that what you
had in mind?

However, our once_flag can store a result of a user-defined type, which may
therefore require proper destruction, so that it can notify other processes,
send network packets, write to a file, or whatever; this therefore needs
dealing with somehow before process termination.
