I have no problem with having more space available than guarantied by
the value of receive_room. But what I see is that the value can be less!
Data will be lost.
My test showed:
data to queue=201
receive_room (guarantied space) =287
real space in queue =0
In the last mail I attached the code for printing, the read_lock was only
added to show a constistant view of all current values.
