From sh(1) man page:

   Built-in Commands
     This section lists the commands which are built-in because they need to
     perform some operation that cannot be performed by a separate process.
     In addition to these, a built-in version of the test(1) command is pro-
     vided for efficiency.
                                                                                       
                                             
     :       A null command that returns a 0 (true) exit value.

It seems that many daemons are not stopped properly...
