It was a known problem, but you are the first to provide an easy way to
reproduce it.  Thanks!

Having reproduced it, I realized that I'm an idiot :-( ... an
SSL_ERROR_WANT_READ return from SSL_read() shouldn't be treated as
an error at all, it just means "no data available yet".  The fix
is in 7.3 CVS tip.
