Right. Please just write the new copy out at the end, and make the
original file open be read-only.
Also, the "good" way to rewrite files is not to unlink and create a
new file with the same name on top, but to create a new file with a
new name, and then rename on top of the file. That way you never get
half-way done files when somebody ^C's in the middle, but all or
nothing.
Trying to figure out why a build doesn't work when there is some
half-created new file can be a real pain in the arse.
