The close method also remover the file from the cache if there are no
more references to it

https://github.com/PyTables/PyTables/blob/6fccb7495ba1bc758c7b04960fe1cd392abe9b96/tables/file.py#L2098

Anyway yes, if you have some problem with the file caching system
please file a bug report on github.

Of course test scripts or patches are very welcome.

ciao
