 From src/balsa-index-threading.c:

/*
  * This file includes two message threading functions.
  * The first is the implementation of jwz's algorithm describled at
  * http://www.jwz.org/doc/threading.html . The another is very simple 
and  * trivial one. If you confirm that your mailbox includes every 
threaded  * messages, the later will be enough. Those functions are 
selectable on
  * each mailbox by setting the 'type' member in BalsaIndex. If you 
don't need
  * message threading functionality, just specify 
'BALSA_INDEX_THREADING_FLAT'.  *
