 since it is indeed a "get counts".  It relies on the assumption that "for each 
FileSystem.get(..) call, the must be exactly a close() call."  I think this is 
not easy to enforce.

> The way {{FileSystem#close}} works is very problematic.  Since the 
> {{FileSystems}} are cached, any {{close}} by any caller will cause problems 
> for every other reference to it.  Will add more detail in the comments.
