Here is my experience (running "make doc-clean doc-uninstall" in between 
each attempt)

- with MAKE="make -j6" and MAKEFLAGS="-j6", it succeeds about half the time 
(succeeded 2 out of 5 attempts)
- with MAKE and MAKEFLAGS unset, it succeeds about half the time (succeeded 
3 out of 5 attempts)
- using "sage --docbuild all html", it worked every time (succeeded 5 times 
in a row)
