Hey @pwolfram, I installed your branch and tried to open_mfdataset on 1474 hdf5 files.

I got the following: File "/users/noel/.conda/envs/python3/lib/python3.6/site-packages/xarray/backends/api.py", line 524, in open_mfdataset File "/users/noel/.conda/envs/python3/lib/python3.6/site-packages/xarray/backends/api.py", line 524, in <listcomp> File "/users/noel/.conda/envs/python3/lib/python3.6/site-packages/xarray/backends/api.py", line 299, in open_dataset File "/users/noel/.conda/envs/python3/lib/python3.6/site-packages/xarray/backends/netCDF4_.py", line 203, in __init__ File "/users/noel/.conda/envs/python3/lib/python3.6/site-packages/xarray/backends/netCDF4_.py", line 178, in _open_netcdf4_group File "netCDF4/_netCDF4.pyx", line 1848, in netCDF4._netCDF4.Dataset.__init__ (netCDF4/_netCDF4.c:13992) OSError: Too many open files
