Motivation: Existentials are boxed if they are wider than 24 bytes. A number of value types in NIO are implemented with storage classes so that the alloaction is only paid for once. However, existential errors are treated differently, they are unconditionally boxed. Implementing errors with storage classes therefore introduces an unnecessary allocation. Modifications: - Remove the storage class for FileSystemError - Remove the copy-on-write test Result: Fewer allocations
