  * PipeRoutesFilteredCount()

records.

a certain neighbor (if multiple neighbors are connected to
the given table).

ced455ef7b Cache redesign - Parsed and Meta cache separation 
* seperate Parsed and Meta cache, so that they may be locked independently
* extend the RunAndParse() function to allow the caller to specify a

  callback for RunAndParse() to update the Meta cache
