Writing (short messages) to a pipe also has atomic guarantees that can make having multiple writers perfectly reasonable.

Is that actually true? It may be guaranteed on Intel x86 compatibles and Linux (because of the string operations available in the x86 instruction set), but I don't thing anything other than an IPC message has a "you can write a string atomically" guarantee. And I may be misremembering that.
And even if it's part of the SUS, how do we know this is true for non-UNIX compatible systems?
