+
+	* globals.cc (exit_states): Renumber so that ES_EXIT_STARTING is first,
+	as intended.
+	* sigproc.cc (wait_sig): Only stop accepting signals after
+	exit_state > ES_EXIT_STARTING.
+
+2013-01-03  Christopher Faylor  <me.cygwin2013@cgf.cx>
+
+	* sigproc.cc (exit_thread): Set thread signal mask so that no signals
+	are sent to an exiting thread.
+
+2013-01-02  Christopher Faylor  <me.cygwin2013@cgf.cx>
+
+	* sigproc.cc (no_signals_available): Remove exit_state test since
+	signals are available in a limited fashion when exiting.
+	(sig_dispatch_pending): Ditto.
+	(sig_send): Ditto.
+	(exit_thread): Rearrange to avoid an unnecessary DuplicateProcess when
+	exiting.
+	(wait_sig): Allow special signals when exiting.
+
+2013-01-02  Christopher Faylor  <me.cygwin2013@cgf.cx>
+
+	* DevNotes: Add entry cgf-000020, relating to previous checkin.
+
+2013-01-02  Christopher Faylor  <me.cygwin2013@cgf.cx>
+
+	* cygtls.h (_cygtls::signal_exit): Delete from class.
+	* exception.h (cygwin_exception): New class.
+	(cygwin_exception::dumpstack): Declare new function.
+	(cygwin_exception::context): Ditto.
+	(cygwin_exception::dump_exception): Ditto.
+	* exceptions.cc (cygwin_exception::dump_exception): Move into
+	cygwin_exception class.  Accommodate new variable names.
+	(cygwin_exception::dumpstack): Ditto stackdump -> dumpstack.
+	(exception::handle): Move andreas processing earlier.  Defer signal
+	processing decisions to the signal thread where they belong.  Pass
+	exception information to sig_send via new siginfo_t si_cyg field.
+	(ctrl_c_handler): Wait for SIGHUP signal to be processed since it could
+	cause a process exit and we don't want races with thread exit lock.
+	(signal_exit): Move back here from sigproc.cc.  Modify arguments and
+	remove from sigpacket class.  Decide when to dump core based on signal
+	type.
+	(sigpacket::process): Handle exiting signals in context of threads
+	rather than in the signal thread.  Signal debugger on non-Windows
+	signals.  Remove setup_signal_exit call.
+	* sigproc.cc (no_signals_available): Remove argument.
+	(signal_exit_code): Delete.
+	(close_my_readsig): Ditto.
+	(_cygtls::signal_exit): Move to exceptions.cc.
+	(sigproc_terminate): Don't attempt to terminate signal thread.
+	(setup_signal_exit): Delete.
+	(exit_thread): Use new si_cyg entry in siginfo_t.
+	(sig_send): Just use empty initializer for si.  Accommodate change in
+	no_signals_available argument.
+	(wait_sig): Remove attempt to "go asynchronous" on process exit.
+	Delete __SIGEXIT handling.  Don't ever exit.
+	* sigproc.h: Remove __SIGEXIT from signal enum.  Renumber.
+	* include/cygwin/signal.h (siginfo_t): Add si_cyg entry.
