What is wrong with creat() ?
from 'man 2 creat': creat() is equivalent to open() with flags equal to 
We want to create the file if it doesn't exist and truncate it if it does.

The only issue I can think of is that no additional flag can be passed 
to creat(); fcntl can alter some of them.  But will we need any ?
