Description Johnny Willemsen 2009-01-12 07:42:03 CST 
when one server is used with 300 clients we see a race condition when multiple server threads wait for the connection back to the client.

        * tao/Transport.cpp (register_if_necessary):
          Don't check if the transport is registered, we could get a thread
          switch between the check and the registration. Also only when the
          register_handler returns -1 we have a failure, with 1 it is already
          registered. This fixes bugzilla 3543

reopen, with 1000 clients things still fail, there can only be 512 connections in the cache, seems a race conditions in the transport cache
