It seems that connectionless WSP code logs empty datagram
properly but does not release memory in this case. Can
you fix this, having a stress test program for wap helps
in this regard.

fresh starting actually at:

     Wapbox:  8048K        4160K
     Bearbox: 7680K        3760K

should be             now?

Yeah. I actually run stress tests one hour, 350 msg/s, with no non-static
leaks in bearerbox. Wapbox leak is smallish, because empty
message is an exception.
