       dnsjit.core.thread - POSIX thread with separate Lua state

SYNOPSIS

         local thr = require("dnsjit.core.thread").new()
         thr:start(function(thr)
             print("Hello from thread")
             print("got:", thr:pop(), " = ", thr:pop(3))

         thr:stop()

DESCRIPTION

       Start  a  new POSIX thread with it's own Lua state.  Sharable objects can be passed to the
       thread by pushing and poping them of the thread stack.  The Thread object  and  any  other
       objects passed to the thread needs to be kept alive as long as the thread is running.

   Functions
       Thread.new()
              Create a new Thread object.

       Thread:log()
              Return the Log object to control logging of this instance or module.

       Thread:start(func)
              Start  the  thread  and  execute  the given function in a separate Lua state, first
              argument to the function will be the Thread object that created it.  Returns  0  on
              success.

       Thread:stop()
              Wait for the thread to return.  Returns 0 on success.

       Thread:push(...)
              Push  string(s),  number(s) or sharable object(s) onto the thread stack so they can
              be retrieved inside the thread using pop().  The sharable  object(s)  needs  to  be
              kept alive as long as the thread is running, strings and numbers are copied.

       Thread:pop(num)
              Pop value(s) off the thread stack, should only be called within the thread.  If num
              is not given then one value is poped.  Returns nil if no values  are  left  on  the
              stack.
