+code modules, and is safe to use in production environments.  Normally, when a
+bug is triggered in native code, the @code{node} process simply ends with no
+helpful information.  In production, this can manifest as worker processes
+restarting for seemingly no reason.  Running @code{node} in @code{gdb} is
+messy and infeasible for a production environment.  Instead, this module will
+sit unobtrusively doing nothing (zero perf impact) as long as Node.js is
+well-behaved.  If a @code{SIGSEGV} signal is raised, the module will print a
+native stack trace to both STDERR and to a timestamped file.")
