+/// Prints the current backtrace, even in a signal handlers.
+///
+/// Since `backtrace` requires locking and memory allocation, it cannot be used
+/// from inside a signal handler. Instead, this uses `libunwind` and `dladdr`,
+/// even though both of them are not guaranteed to be async-signal-safe, strictly
+/// speaking. However, at least LLVM's libunwind (used by macOS) has a [test] for
+/// unwinding in signal handlers, and `dladdr` is used by `backtrace_symbols_fd`
+/// in glibc, which it [documents] as async-signal-safe. In practice, this hack
+/// works well enough on GNU/Linux and macOS (and perhaps some other platforms,
+/// but we haven't enabled those yet).
+///
+/// [test]: https://github.com/llvm/llvm-project/blob/a6385a3fc8a88f092d07672210a1e773481c2919/libunwind/test/signal_unwind.pass.cpp
