Interresting, flock()'s third parameter is absolutely useless if it's not
passed by reference (all the code explicitly checks for PZVAL_IS_REF(arg3)
and ignores if it's not), does anyone with historical knowledge of this
function have an idea why this arg isn't force by ref? Unless I'm missing
something off-the-wall, it looks like a bug fix for the 4_3 branch.
