1) Xorg is mapped twice - IMHO first is text/rodata second is data. But
what "REF" really means here and why it is 2 once and 1 second.
2) what really PRES ("private resident") means? df (default) mappings are
IMHO anonymous maps==private data of process. so why RES is nonzero while
PRES is zero, while on shared code PRES is nonzero and large. what does it
really means?
thanks.
