+Subject: [PATCH] Re-enable SIGIO when waiting for events
+Date: Sat, 11 Jul 2015 12:58:00 +0100
+
+Pasting a large string into an Emacs tty frame causes
+keyboard.c:kbd_buffer_store_buffered_event to call ignore_sigio()
+which sets SIGIO to SIG_IGN.
+
+Unfortunately no-one seems to ever re-enable the SIGIO handler.
+
+This leads to timeouts when attempting to paste into an Emacs X11
+frame as reported at
+http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16737 .
+
+It appears that keyboard.c:kbd_buffer_get_event used to re-enable the
+signal handler but that was removed as part of a large signal-handling
+clean up in 4d7e6e51dd4acecff466a28d958c50f34fc130b8.
+
+Reinstating the re-enabling of SIGIO in kbd_buffer_get_event solves
+the problems reported in bug 16737 for me.
+
+* src/keyboard.c (kbd_buffer_get_event): Re-enable SIGIO when waiting
+  for event.
