New submission from Barney Gale <barney.gale at gmail.com>:
I have a scratchy patch that replaces pathlib's globbing implementation with glob.glob(), which gained a `root_dir` argument in bpo-38144
Encouraging timings:
$ ./python -m timeit -s "from pathlib import Path; p = Path()" -- "list(p.glob('**/*'))"
Unpatched: 43.2 msec per loop
Patched: 4.37 msec per loop
$ ./python -m timeit -s "from pathlib import Path; p = Path('/usr/')" -- "list(p.glob('lib*/**/*'))"
Unpatched: 248 msec per loop
Patched: 56.8 msec per loop
$ ./python -m timeit -s "from pathlib import Path; p = Path('/usr/')" -- "list(p.glob('lib*/**/'))"
Unpatched: 78.3 msec per loop
Patched: 2.23 msec per loop
Patch to follow.
