[issue33451] Start pyc file lock the file

[Jean-Louis Tamburini]

New submission from Jean-Louis Tamburini <jeanlouis at solutions66.com>:

Python v3.6.4:d48eceb
Windows 10.0.16299

I search on Internet and I don't find why Python Interpreter (v3.6.4) do that. With python 2.7, I don't have this "problem".

When I launch script like : 
c:\Python364\python.exe compile.py
While the execution, I can rename/modify the file "compile.py". 

But, when I compile the file to .pyc (with py_compile with an another script), and I launch the pyc like :
c:\Python364\python.exe dummy.pyc
While the execution, I CAN'T rename/modify the file because is locked by Python Interpreter. 

It's normal ?
