It uses the hostname information for locking files, etc.  This is
particularly useful when on a network.

I think that if you are experiencing delays, then your /etc/hosts file
is probably faulty.  Make sure the first line looks like

   127.0.0.1       paco    localhost

where, e.g., paco is the hostname.  Also check your /etc/nsswitch.conf
contains

   hosts:          files dns

and not, e.g.,

   hosts:          dns files

These changes should solve the delay problem.
