I missed the start of this but I assume it's a discussion of portable
nonblocking socket code, I wrote my own wrappers for this which work under
every Unix I've been able to get my hands on as well as Win32, if whoever's
working on this for GPG wants the code they can grab it from the latest
cryptlib version, ftp://ftp.franken.de/pub/crypt/cryptlib/beta/cl30beta05.zip,
as misc/net_tcp.c.
