Detailed Description

Functions to produce backtraces on bugs, crashes, or assertion failures.

Currently, we've only got an implementation here using the backtrace() family of functions, which are sometimes provided by libc and sometimes provided by libexecinfo. We tie into the sigaction() backend in order to detect crashes.
