Right now we write to the result file directly, so a poorly timed ^C could cause a partial, possibly corrupt, file to be written. Let's approach this a different way:

OPEN_READ opens the file directly for reading.
OPEN_WRITE opens a temporary file for writing. Calling close() on the file structure will then trigger a rename, replacing the old file in the filesystem.
