[issue9247] imp.reload() doesn't take import lock

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

I am not sure this is important or now, but reload() (imp.reload() in 3.x) doesn't take the import lock when reloading:

$ echo 'import imp; print("lock held =", imp.lock_held())' > foo.py
$ ./python -c 'import imp, foo; imp.reload(foo)'
lock held = True
lock held = False
