* Sync-up with 3.4 to make maintenance easier.Raymond Hettinger2013-03-091-9/+7

* Another nit.Raymond Hettinger2013-03-041-1/+1

* Fix other re-entrancy nits for the lru_cache.Raymond Hettinger2013-03-041-7/+11
| | | | | | | | | | | | | | Keep references for oldkey and oldvalue so they can't trigger a __del__ method to reenter our thread. Move the cache[key]=link step to the end, after the link data is in a consistent state. Under exotic circumstances, the cache[key]=link step could trigger reentrancy (i.e. the key would have to have a hash exactly equal to that for another key in the cache and the key would need a __eq__ method that makes a reentrant call our cached function).
* Remove dependency on dummy_threading (to solve a bootstrap problem).Raymond Hettinger2013-03-021-1/+4
