As far as I recall, GNU make on *BSD does support SIGINFO (Not a standard tool, but obviously an established one).
The developers of strace have expressed interest in SIGINFO support to print tracer status messages (unfortunately, not on a public list). Computational software can use this instead of stderr progress spam, if run in an interactive fashion on a terminal, as it frequently is. There is a user base, it's just not very vocal on kernel lists. :) [unhandled content-type:application/pgp-signature] | |
