+/// @file Crash handler for Lix that prints back traces (hopefully in instances where it is not just going to crash the process itself).
+/*
+ * Author's note: This will probably be partially/fully supplanted by a
+ * minidump writer like the following once we get our act together on crashes a
+ * little bit more:
+ * https://github.com/rust-minidump/minidump-writer
+ * https://github.com/EmbarkStudios/crash-handling
+ * (out of process implementation *should* be able to be done on-demand)
+ *
+ * Such an out-of-process implementation could then both make minidumps and
+ * print stack traces for arbitrarily messed-up process states such that we can
+ * safely give out backtraces for SIGSEGV and other deadly signals.
