SIGTERM is no longer caught to call sys.exitfunc.
This change was made long ago but the documentation was never updated.

Python installs a small number of signal handlers by default:
\constant{SIGPIPE} is ignored (so write errors on pipes and sockets can be
-reported as ordinary Python exceptions), \constant{SIGINT} is translated
-into a \exception{KeyboardInterrupt} exception, and \constant{SIGTERM} is
-caught so that necessary cleanup (especially \code{sys.exitfunc}) can
-be performed before actually terminating. All of these can be
+reported as ordinary Python exceptions) and \constant{SIGINT} is translated
+into a \exception{KeyboardInterrupt} exception. All of these can be
overridden.

This value is not actually defined by the module, but can be set by
