AFAIK this is no longer true after Python 3.4.

I took a look with @delandmeterp and found that manually adding a `gc.collect()` (which collects all cycles) after deleting `temp` fixes the issue. The cycle was keeping the object around longer than expected, resulting in the lock error. It's not clear to me where the cycle is coming from (I'm not familiar with xarray internals), but this is indeed the issue.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,460254571
