I’m quite familiar with strace, but I rejected that out of hand at the time,
since most Perl code is running way above the OS’s syscall interface.
There are only a couple of cases I can think of where what it says might help.
E.g. stuck on accept(2).
No, I really do want to be able to produce a Perl-level stack trace, on demand,
without killing the program, as via Carp::confess().
It looks like “perl -d” can’t attach to a running program, either, which would
let me use some of these fine Perl modules to produce a backtrace.
I found a partial solution, though:
https://metacpan.org/pod/App%3a%3aStacktrace
Unfortunately for me, it requires Perl 5.10, and this problem happened on a box
that’s still running 5.8. (Don’t ask, can’t avoid that.)
