@shoyer, unfortunately these opendap datasets contain only 1 time record (1 daily value) each. And it works fine on Linux with file_cache_maxsize=128, so it must be some Windows cache thing right?

So since I just picked file_cache_maxsize=10 arbitrarily, I thought it would be useful to see what the maximum value was. Using the good old bi-section method, I determined that (for this case anyway), the maximum size that works is 25.

In other words: ``` xr.set_options(file_cache_maxsize=25) # works

xr.set_options(file_cache_maxsize=26) # fails

``` I would bet money that Unidata's @DennisHeimbigner knows what's going on here!
