My (?:m(?:is)?)?adventures in the world of POSIX signals continue. Now to followup on my own patch of two years ago [1], here is support for SA_SIGINFO (see man sigaction), which allows additional information to be passed on to the signal handlers (beyond the signal number).
I am not entirely proud of the argument passing scheme to the signal handler (the name of the signal, a hash ref with the POSIX/SUSv3 fields unpacked, and the binary blob of the whole siginfo struct) but I tried to find a solution somewhere between being a POSIX purist and a portable pragmatist.
