Out-of-band bit for exceptional return and errno replacement

Abstract

We propose a mechanism for out-of-band return of exceptional conditions that are designed, among other things, to replace errno and similar thread-local mechanisms for error return, and to allow C libraries and other programming languages to implement value based exception return on top of it. Our method is designed to be conservative: there is no need of ABI replacement for platforms, only amendment, and existing executables and compiled libraries remain valid.
