[THREDDS #OIV-218948]: caching netcdf variables in thredds

Yes. The class in question is FileCache:
https://github.com/Unidata/thredds/blob/5.0.0/cdm/src/main/java/ucar/nc2/util/cache/FileCache.java
The clearCache(), eject(), and cleanup() methods actually close the
NetcdfFiles, which releases the underlying file handles.
Look for "cacheLog" to see the messages that are logged.

I had the same thought. As I did not write any of the code I can only
speculate. Maybe FileCache is used somewhere to manage writeable files?
