Description

/var/run/sswsyncd/sswsyncd.socket seems to only allow one client, this is problematic especially when we have bcmsh enabled. If some one is using bcmsh, and bcmcmd will hang there. Ever worse, bcmsh does not time-out, so bcmcmd could be blocked there forever until you kill the bcmsh.

Steps to reproduce the issue:

1. run bcmsh
   a# bcmsh
   Press Enter to show prompt.
   Press Ctrl+C to exit.
