Name service caching behaviour

Hi Guys,
  It appears that hosts names are always cached somewhere even if nscd is disabled. Here is a test case I ran:

           1.  on termial 1, disable nscd:
                # svcadm disable name-service-cache
                # svcs name-service-cache
                 STATE          STIME    FMRI
                disabled       15:18:55 svc:/system/name-service-cache:default

            2. on termial 2, run first sftp session:
            sbpsvrwm691% sftp gcsscinca@fts.jpmchase.com
            sbpsvrwm691% sftp> exit
            sbpsvrwm691%

            3. on termial 3, and 4, start snooping on all interfaces
            # snoop -o /tmp/snooper5 -d bge0
            # snoop -o /tmp/snooper6 -d bge1

            4. on termial 1, run second sftp session:
            sbpsvrwm691% sftp gcsscinca@fts.jpmchase.com
            sbpsvrwm691% sftp> exit
            sbpsvrwm691%

            5. stop snooping, and print the result:
            # sync;sync;sync
