[THREDDS #OPV-470285]: TDS error I've never seen before: "spi is null, perhaps file has been closed"

Hi Rich,

I've reproduced the failure, though I'm getting a different error message:

The failure is in the HDF5 IOSP, but I don't think it actually has anything to 
do with that. The next step is to reproduce with plain NetCDF-3 files.

My working hypothesis is that OpendapServlet is keeping NetcdfDataset objects 
around in memory between calls, while the NcML aggregation machinery is 
aggressively closing them in the background to save memory. Then OpendapServlet 
attempts to read from a dataset that's been closed.

Your support tickets are never easy, Rich, but often instructive.
