It's not a problem at all. You never can expect that a single read()
will return all data -- the library (just like the read() system call)
cannot know where to stop.
The reason for the behaviour you observed is not just some peculiarity
of SSL_read: That data is split in 16K blocks already when it is
written. This is the maximum record size allowed by RFC 2246.
