RFC: patch to lin-lwp.c

[J. Johnston]

The attached patch is created to deal with the problem as discussed on:

   http://sources.redhat.com/ml/gdb/2003-08/msg00043.html

The fix does two things:

   1. it sets the resumed flag for threads we stopped when the main thread
      exited and then resumed
   2. changes the running_callback to include threads that have events
      pending on them that will be caught on the next wait

Ok to commit?

	* lin-lwp-wait.c (stop_and_resume_callback): Set the resumed flag
	for any lwp we resume.
	(running_callback): Add lwps that have pending status events
	against them to be considered running.
