   OK. So I have tested following branches mcumgr_changes@zephyr  and run_zephyr@modules/lib/mcumgr. No rebasing done.
   
   SMP over shell, but no terminal connected to the shell, from  PC, at the same time when MCUMGR is running on the PC.
   
   Using script:
   `$$ UART=/dev/ttyACM0; BAUD=57600; while [ ! -e ~/tmp/mcumgr_stop ]; do time sudo ~/go/bin/mcumgr -t 1200 --conntype serial --connstring dev=$UART,baud=$BAUD image upload ~/nordic-src/ncs/nrf52840_pca10056/Disco.bin; if [ $? -ne 0 ]; then echo "Error"; fi;  sudo ~/go/bin/mcumgr -t 1200 --conntype serial --connstring dev=$UART,baud=$BAUD image list; done`
   
   I have counted errors or total stoppages. 
   
   In case when using board USB serial (/dev/ttyACM0) I have faced some timeouts on binary every few (3-4) transfers with baud=115200; after modifying DTS file to use 57600 speed (and MCUMGR)  have 100% success ratio in transfers for about 20 transfers before disconnecting.
   
   When I have connected directly to Tx/Rx of IC, bypassing the USB interface on board, both baud rates have me 100% success ratio in transmission for about 30 minutes (~60 transfers).
   
   I have not seen regression in transfer success rate.
