Hi Andrey,
	If I've correctly understood, using the low level interfaces, I can
load only a portion of the file, but i need all the file loaded, or  at
least, a way to load in sequence a little portions of the file. But the
primary question is: is it normal that parsing a 27,6 Mb yaml file
result in an istance of more than 1 Gb?
Anyway, if there is a more easy doc on this low-level interfaces, can
you please send me the link? The PyYAML documentation isn't very clear
for me on this argument.
Thanks,
Dario.
