  - If mail is left on the POP server when
      the user checks, the leds are not 
      reset.
      This apparently happens with the QPOP
      mail server.
      Maybe use pressing SCROLL LOCK as signal
      to reset status??

  o Ledmail will clear all LEDS even if they
      are not in use.  Can use KDGKBLED to
      get status and then only set the ones
      that are set for mail accounts.

         Now uses KDGKBLED and only sets LEDs
         that have mail accounts assigned,
         but behaves strangely under X, but fine
         at a VT.
      INVESTIGATED 7/12/00
         Changed KDGKBLED to KDGETLED.

  o Leaking file descriptors, perhaps only on 
      an error connecting to a server.

  o If a mail server cannot be contacted when
      ledmail is first ran, it will be omitted
      from the mail check for ever.  Further- 
      more, if no mail server can be contacted
      led mail will fail to start.  This was 
      deliberate, but might be annoying?
      FIXED 10/12/00
        Now marks the failure as a mail check error
        and will repeat DNS lookups, connects etc,
        until the service is initialised.

  - Maybe a problem if the connection is dropped
      during a check, causing read() to block
      indefinately.  Or it might be due to the
      changing IP address of my dialup machine.
      INVESTIGATED 10/12/00
        Added debugging output to check for this.
        Awaiting the situation to happen again.
      FIXED 28/04/01
        Wrapped read() with a timedread function.
