This command will re-execute the mud, whilst attempting to keep players connected. It involves a nasty trick with a temporary file, the close-on-exec flag and exec (2).

  The mud will be reset as a side effect.
  
  Please note that POP connections will be screwed when you do this, people's mails will be interrupted, etc, and any changes made to the MUD will be lost.
  
example:

  ^W>^nreboot
  [global] (^pOrange^n) reboot begun
  Saved ^pOrange^n at Muon's Bar.
  [global] reboot finished
  ^W>^n
