When would this be useful? Consider that TCP itself doesn't offer this, so
applications requiring it should be rare.

Sockets don't work that way though - the OS doesn't tell you that an EOF
has happened *before* reading all the outstanding data. Checking _eof is
not just undocumented, but also unreliable (it might not be set).

If you really think it is useful, please state a convincing use case, and
how you think it should behave.
