Yes, if you're making calls into the tcp stack from more than one
thread, or from an interrupt handler or similar and the application (for
example), you need to protect the stack with locks.  The higher level
"sequential API" and "sockets API" do this for you, but the raw API that
you're using doesn't.  I think - if anyone knows otherwise (things might
have changed since I last looked!) please correct me.
