Apologies, I transcribed that incorrectly. I do have `(identity 
#o444)`.

Subsequent tangles did not fail for me. I just tested by building 
Org from a2cb9b853's parent: f84033b08.
Multiple tangles work with no permission errors on subsequent 
tangles.

Here's my init.org, if that's useful:

Unfortunately, I don't have much use for the workaround if 
subsequent tangles will fail.
I currently have an after-save-hook function which tangles the 
files if I've edited any of the
src blocks. It's very convenient and I often will edit/tangle 
files set up like this multiple times.
