I could rely on that if the server sent them only as a response to _my_
binary data. If it is this:

S: <proceed/>
C: Binary greeting
S: Binary response

Then everything is OK, because I can get ready for binary before I send
my binary part. I'm not sure it is this way, but whenever I looked on a
TCP dump or expected this behaviour, it always worked this way.

Of course, If this could happen too:
S: <proceed/>
S: Some binary data
C: Binary response

Then I would be out of luck and couldn't expect it to come out as two
separate reads.

I expect the proceed is ment as server telling me he is ready for _my_
binary data. It won't send me any binary data unless I do it first.

Have a nice day
