    If you're fortunate enough to find yourself on a platform without a SemLockType ¯\(ツ)/¯ and see this:
# python -m multiprocessing
Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 163, in _run_module_as_main
  File "/usr/lib/python2.7/runpy.py", line 111, in _get_module_details
  File "/usr/lib/python2.7/multiprocessing/__init__.py", line 84, in <module>
ImportError: /usr/lib/python2.7/lib-dynload/_multiprocessing.so: undefined symbol: SemLockType

But the code your running "needs" a threadpool. Why not patch out multiprocessing with something ✨ synchronous ✨
mkdir multiprocessing
touch multiprocessing/__init__.py

Place the file below as multiprocessing/pool.py and you have a synchronous "threadpool" 🎉
	class Result():
	def __init__(self, result):
	self.result = result
	def get(self, timeout):
	return self.result
	class ThreadPool():
	def __init__(self, processes):
	pass
	def apply_async(item, args, kwargs):
	return Result(item(args, *kwargs))
