>Description:
It is not possible to start portmap listening solely to the localhost (127.0.0.1).  The problem is that portmap always appends 127.0.0.1 to every list of -h options (addresses) passed in, and then dies when tryin to bind to the localhost port the second time.
>How-To-Repeat:
Run "portmap -h 127.0.0.1".  portmap will die.
>Fix:
One solution would be to have portmap not add 127.0.0.1 automatically to its list; this functionality is probably not a good design.  But due to backwards compatibility, a more desirable option would be to just have to check if 127.0.0.1 is in hosts[] before adding it a second time to the list of addresses to bind to.
