It depends on the system & location. It's possible to set up
directories with permissions that allow you to create files but
not delete them, in which case you'd either (1) create the file
and possibly fail on subsequent tests because the file already
exists; or (2) litter the directory with tmpnam()-like results
that you were unable to delete.
It's ugly, I've encountered it, and haven't found a good
universal solution myself.
