Tests probably shouldn't be using stdio anyway, except perhaps for the 
wrapper used when we run remotes and such to print the PASS/FAIL message.

One could argue a better direction would be to change calls into stdio 
to instead call some other function defined in the same .c file.  That 
"other function" would be marked as noinline.  That would help minimize 
the possibility of compromising the test.
