This has been fixed for some time now.

When an unnamed file handle is created (e.g. by specifying a quoted string in a context where a file handle is required), PSPP currently retains a file handle data structure in memory for the remainder of the run (or until CLOSE FILE HANDLE is used). But in fact there's no reason to retain it beyond the expiration of the last reference to the file handle (which is probably the execution of the next procedure). We should try to free such file handles at that time.

Named file handles (e.g. those created on an explicit FILE HANDLE command) are different, because we need to retain the name-to-file mapping and possibly some metadata (e.g. record length) also.
