It requires setting a single bit 'socket terminated' and then checking
this, there is no need for memory barriers, it's atomic by definition.
 No thread will ever unset that bit again so there'll be no conflicts.
 The terminating thread will be called once in the lifetime of the
application.

How does this create 'grave performance impacts'?
