Non-stop mode is meant for processing files, not input at the terminal! 
On my system (TL2013, Mac), I see

palladium:siunitx joseph$ pdftex -interaction=nonstopmode

This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013)
  restricted \write18 enabled.
**Please type the name of your input file.
**

for which \relax is an emergency stop: no file name. That's entirely 
consistent with what nonstopmode is for.
