	workspace	A simple, reference implementation of a, workspaces
	tray		A simple, reference implementation of a, status icon tray
	cool-old-crt	Old CRT emulator, like cool-old-term but display-wide
	kbd2rat		Control the rat cursor with the keyboard
	multikey	Bind keys to send sequences of keys
	iclipboard	User-private interdisplay clipboard

Missing commands:

	reg		Command line interface for the protocol registry
	conf		Command line interface for reconfiguring servers
	clip		Command line interface for the clipboard

Need testing:

	registry

	kkbd, on a SPARC

Fast lanes
Optimise use of mutexe by replace them with rwlocks
Listen for `Command: reregister`
Register protocols
Make it possible to forbid unauthorised servers for listening, needed for secure password fields
  I guess we can let servers create their own abstract sockets, report them to mdsinitrc and
  let mdsinitrc export appropriate environment variables.
Signals that should be supported, and be replaced with realtime signals if not defined:
  SIGDANGER  system or process is running out of memory
