File will be closed when the pool gets destroyed.
Closing here has little advantages cause the pool
memory will rise over time so you cannot be sure
the provided pool won't get dirty if open fails.

It would be better to create a sub pool for shared
memory which will ensure that both parent pool
doesn't leak memory and that file is always closed.
Repeating apr_file_close across all possible return
failures just make no sense when we have pools.
