“call-with-atomic-output-file” in ’collects/racket/file.rkt“ attempts to
create a temporary file in whatever the result of ‘(path-only path)’ is,
or in the current directory.

What file is it trying to compile?

The root of this path appears to be ‘collectsdir’, which is set up at
‘configure’ time.  This directory seems to be correct, because it
contains Racket modules.  We would only need to ensure that compilation
does not use this directory by default.

I’m guessing that this is controlled by ‘do-get-compilation-dir+name’ in
‘collects/compiler/compilation-path.rkt’.

Does this make any sense?
