"returns ... the first error" was misleading or at least confusing:
in case a Read results in an error with non-zero bytes read, and the
subsequent Write also results in an error, the error from Write is
returned, which is the second one (in the temporal dimension).

to CloseWithError(nil) because it can remove a branch from their error
handling code where they want to close the pipe in the appropriate way.
