+ Subject: [PATCH] patcher: Call get_hub() before beginning monkey-patching

+ 

+ In some cases -- notably with Python 2.7.13 and the default hub -- the

+ process of importing the hub involves calling code in a module we

+ monkey-patch. This leads to recursive imports: the first eventlet

+ function will call get_hub(), which will try to import the hub, which

+ will call a monkey-patched module, which will call get_hub() and try to

+ import the hub again.

+ 

+ To avoid this, make sure the hub is fully imported before

+ monkey-patching anything.

+ 

+ Closes #401.
