andrequires each site you want to bt to be annotated explicitly. I forgot about backtrace() completely when I wrote
mine,and I prefer the control libunwind gives me anyway, but the reduced dependency would be nice. Especially since
backtrace()is in FreeBSD too.
Just as a datapoint regarding this; backtrace() is not available in OpenBSD,
but there is a library in ports which implements it, libexecinfo.
