Yes. An attempt is made to map some of the errors to I/O. Anyway, if sb
wants to support and modernize them, I have no problem with that. But that
hasn't happened since 2005-2007 or so.

That would also make it possible to directly map socketerror to
getlastresult/fpgeterrno, instead of caching it in another threadvar.
