+
+# The rationale for this is described here:
+# http://www.cons.org/cracauer/sigint.html
+#
+# Basically, bash will not exit on SIGINT immediately if it waits
+# for a child. It will wait for the child to exit.
+# If child exits NOT by dying on SIGINT, then bash will not exit.
+#
+# The idea is that the following script:
+# | emacs file.txt
+# | more cmds
+# User may use ^C to interrupt editor's ops like search. But then
+# emacs exits normally. User expects that script doesn't stop.
+#
+# This is a nice idea, but detecting "did process really exit
+# with SIGINT?" is racy. Consider:
+# | bash -c 'while true; do /bin/true; done'
+# When ^C is pressed while bash waits for /bin/true to exit,
+# it may happen that /bin/true exits with exitcode 0 before
+# ^C is delivered to it as SIGINT. bash will see SIGINT, then
+# it will see that child exited with 0, and bash will NOT EXIT.
+
+# Therefore we do not implement bash behavior.
+# I'd say that emacs need to put itself into a separate pgrp
+# to isolate shell from getting stray SIGINTs from ^C.
