----------------------------------------------------------+-----------------
 Several methods in filesystem::path, including remove_all, have an
 overload in which an extra error_code& argument is taken. According to the
 docs, this is supposed to cause failure (other than failure to allocate
 storage) to be reported in the error_code rather than as a thrown
 filesystem_error exception. However, remove_all can still throw
 filesystem_error exceptions because it uses a directory_iterator
 internally but makes no attempt to catch exceptions thrown by it. For
 example, if a subdirectory is deleted by another thread or process just
 before remove_all tries to list its contents, directory_iterator_construct
 will throw a filesystem_error that propagates up to remove_all's caller.

 As a side note, I think path and directory_iterator are both excessively
 exception-happy. It makes them painful to use.
