* thread.c (delete_step_resume_breakpoint): New function.
	Maintain internal consistency of the thread list while deleting
	a step_resume_breakpoint.
	* gdbthread.h (delete_step_resume_breakpoint): Export.
	* breakpoint.c (bpstat_find_step_resume_breakpoint):
	Make thread-aware: don't return a step_resume_breakpoint
	for the wrong thread.
	* infrun.c (wait_for_inferior): Call delete_step_resume_breakpoint
	instead of delete_breakpoint_current_contents.
	(fetch_inferior_event): Ditto.
	(handle_inferior_event): Call delete_step_resume_breakpoint
	instead of delete_breakpoint.
