[ndnSIM] Why some of the expired Interests are not removed from PITs?

[Junxiao Shi]

Hi Carl

This is because nfd::Pit is not “pending Interest table”, but “Interest table”. NFD Interest table contains entries for both pending Interests and recently satisfied Interests.
Read NFD Developer’s Guide “Interest table” section for more information.

Yours, Junxiao
