-be in the poll() and simple OS fail as they re-allocate the same socket
-on which a thread is still waiting. 
-Ideally, you want to set the lock in the disconnect() but that would mean
-very often we'd have to always wait for the end of the poll(), i.e. up to
-100ms for nothing most of the time where if it is in the open(), it is 
-less elegant as closing a socket on which there is a poll() is not good 
-but it's more efficient as it is very rare that you'd have an open() less 
-then 100ms after a close()
+When LMS sends a close/open sequence very quickly, the stream thread might
+still be waiting in the poll() on the closed socket. It is never recommended
+to have a thread closing a socket used by another thread but it works, as
+opposed to an infinite select(). 
+In stream_sock() a new socket is created and full OS will allocate a different
+one but on RTOS and simple IP stack, the same might be re-used and that causes
+an exception as a thread is already waiting on a newly allocated socket
+A simple variable that forces stream_sock() to wait until we are out of poll()
+is enough and much faster than a mutex
