I have a few failing tests here on the scipy backend and I'm not really sure what's going on. It seems like it could be related to the `mmap` feature in scipy.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,262930380

I'm wondering what you think? This version more aggressively overwrites existing variables (data_vars and coords).,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,262930380

1) appending to a file with existing data variables
2) appending to a file with existing coordinate variables

I'm wondering if we should disallow 1, in favor of being more explicit. So:

```Python
list_of_vars_to_append = ['var1', 'var2']
ds[list_of_vars_to_append].to_netcdf(filename, mode='a')
# if either var1 or var2 are in filename, raise an error?
```
as apposed to the current behavior which would silently skip all vars already in `filename` and not in  `list_of_vars_to_append`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,262930380
