Sorry for the late response (I've been away); "required" is perhaps putting it strongly, because as you say the information is there, somewhere. However, it would be nice to have, as standardized, that the third argument to the sa_sigaction handler be castable to a ucontext_t, as this would make porting signal-handling code between Linux flavours much easier.
