In Python/import.c, open_exclusive unlinks any existing bytecode file before opening to create a new one.

However, py_compile.compile doesn't unlink before opening, and therefore fails if an existing bytecode file is unwritable.  It would be nice to unlink first in this case too.

It is explicitly documented that existing files are not overwritten and the script fails in this case, so I think this is a feature:
