Description

Steps to reproduce:

  1. nfd-start
  2. ndnpingserver /A & ndnpingserver /B & ndnpingserver /C &

Expected: three ndnpingserver instances start normally

Actual: with high probability, two instances terminate with

ERROR: Failed to register prefix in local hub's daemon
REASON: Face not found

Suggested fix: When RibManager finds the FaceId in rib/register command is non-existent, don't reject the command right away; instead, wait 1 second so that FaceTable has a chance to be up-to-date on newly created faces.

Please review http://gerrit.named-data.net/#/c/1131/1

I think the current approach is not correct and prone to errors, since valid face ID in NFD is not immediately seen by NRD. Delaying registration action is not correct. I would simply ignore invalid faces in RIB (not a big deal) and deal with invalid faces in different way (will create a separate issue for that).
