NBMiner does not support method client.reconnect()

NBMiner 42.3 for Linux
It looks like NBMiner doesn't support client.reconnect. I demonstrate it with MiningRigRental pool.
That pool is different from other pools. Client connects to TCP port 3333 and pool dynamically configures new TCP port and asks miner to reconnect, it uses stratum method client.reconnect.
DEMO, mine kawpow; NBMiner fails to connect to TCP port 3333, the issue:
$ cat test-nbminer-mrr7.sh
#!/bin/sh
POOL="eu-01.miningrigrentals.com:3333"
USER="droidMiner.294955"
PASS="TEST7"
OPTS=""
./nbminer -a "kawpow" -o "stratum+tcp://$POOL" -u "$USER" -p "$PASS" $OPTS $@
$ sh test-nbminer-mrr7.sh

When I use a workaround and configure redirection manually, NBMiner can connect to MRR pool and mine but this is not ideal as this port was dynamically generated and can be changed and after that NBMiner configuration has to be adjusted, again and again and again... :-(

One more DEMO, try to connect to port 3333, this time in verbose mode. It is visible that pool asks miner to reconnect but that request is ignored, the issue:
$ cat test-nbminer-mrr7.sh --verbose

Most of other miners can handle client.reconnect(). An example, gminer already fixed similar issue and can connect directly to TCP port 3333:
$ cat test-gminer-mrr9.sh
#!/bin/sh
POOL="eu-01.miningrigrentals.com:3333"
USER="droidMiner.294955"
PASS="TEST9"
OPTS=""
./gminer -a "kawpow" --server "stratum+tcp://$POOL" --user "$USER" --pass "$PASS" $OPTS $@
Notice, how reconnection from TCP port 3333 to port 50814 is smoothly done. It is cool, isn't it? ;-)
