	* TODO: Add section on Mach.  Stop calling it a "bug list".
	Remove John's name and email address.  Remove item on "always"
	("hook-stop" takes care of this).  Remove item on executables with
	no symbols (this works on some machines, at least).  Remove item
	about calling error() during symbol reading (I think all the important
	ones have been cleaned up).  Revise items about signals and remote
	systems.  Remove section on ^Z requiring several continues to make
	it go (this now works.  Perhaps the item is based on confusion over
	programs (like GDB itself) which catch SIGTSTP and then re-send
	themselves the signal.  PR 2575 might contain relevant info).
