-  Return a copy of the file handle `oldfd`.
-  After a successful return, both `FileHandle` may be used interchangeably.
-  They refer to the same open file description and share file offset and status flags.
-  Calls POSIX function `dup` on Posix platform and `_dup` on Windows

-    # stdoutDuplicate is a copy of stdout FileHandle that points to STDOUT
-    let stdoutDuplicate = duplicate(stdout.getFileHandle())
