Funny how the simple questions sometimes have hard answers :) It turns
out that the program I sent always hung. I added some logic to do a
poll to check for more data, etc. and I think I came upon the root of
the problem.

I found this function in some example code, and it seems to do the trick
-- SSL_pending. It's possible for SSL to read all the data from a
socket, but not make it all available to SSL_read at once (see
http://www.openssl.org/docs/ssl/SSL_read.html). So, even if poll or
select returns 0, we've still got to do an SSL_read if SSL_pending says
there are bytes to read.

I'll see if I can find a good place to put this in the curl code.
Anyone else wanna try too?
