GNU coreutils dd will already support SIGINFO if available (and if dd is recompiled with appropriate headers). dd currently emulates that using SIGUSR1 though as you say that's awkward to support robustly, and there has been a recent GNU coreutils change in relation to that: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=27d2c738
I like the idea of making SIGINFO generally available and GNU coreutils at least would add extra handling to cp etc. if that was the case.
