I think part of the way to address this (too many sync functions) is
follow through on another of Torsten's recommendations - provide
better user-oriented material on using the interface. Most libraries
these days have large numbers of methods/functions; this complaint
usually means "I can't figure out which routines to use" not "there
are too many routines".
