To come back to this, I was looking at moving replack() to close(), but 
noticed that syncToDisc() has the logic "for shapefiles, remove spatial 
index files and create a new index" which calls close. And syncToDisk is 
still called after every change. So should syncToDisk be also moved to 
close(), or at least blocked if an updateMode is active?
