It is. The stuff above is just to say that I evaluate the probability
that any exsisting log suffers from this problem as *very* small.

I see this point. Let's say: we can send it, but we do not expect
other people to send it in cases where it's redundant? 

What I see as important is to keep the load low for people developing
an MRML server.

Q1) sockets do that for you. There can be multiple connections over
one socket. We don't care, we read and write from/to different file
Q2) You can have multiple open sessions for one user. Trouble begins
when a person asks twice for the same session to be opened.
