Right, it is too hard to get this into Libassuan in a flexible way.  You
would end up with something as complicated as the gpgme event code.

If it ever turns out that this is required by a lot of other code, we
can revisit this then.

Fine.  However, gpg-agent heavily relies on nPth semantics.  This is
probably not what you want.

Actually we have a platform independent socket abstraction in libassuan
for that purpose.  Check out how it is done in dirmngr or gpg-agent.

We can talk about neglecting WindowsCE, but Windows is a/the mainstream
platform and thus we should support it.
