From 57380f4e0bbdfa396ed068db6bd867b4fafd9925 Mon Sep 17 00:00:00 2001
From: Daniel Jacobowitz <drow@false.org>

Subject: 	* linux-nat.c (resume_callback): Add more debugging output. 
 (linux_nat_has_pending_sigint): New function, based on 
 linux_nat_has_pending. 	(set_ignore_sigint,
 maybe_clear_ignore_sigint): New functions. 	(stop_wait_callback): Remove
 flush_mask handling.  Honor 	ignore_sigint.  Call
 maybe_clear_ignore_sigint.  Pass NULL 	to recursive calls. 
 (linux_nat_has_pending, flush_callback): Remove. 
 (linux_nat_filter_event): Check for ignore_sigint. 	(linux_nat_wait):
 Remove flush_mask support and call to 	flush_callback.  Use set_ignore_sigint
 and maybe_clear_ignore_sigint. 	* linux-nat.h (struct lwp_info): Add
 ignore_sigint field.

	* gdb.threads/manythreads.exp: Use remote_expect instead of after.
	Add a test for duplicated SIGINTs.
