As long as cthread and pthread are not compatible, nor me. ;)

Is there a replacement for CPROC_SWITCHING and CPROC_RUNNING in
cproc_t->state, to know if a thread has been waken up?

__pthread.state has the following states...
 
 /* Thread state.  */
enum pthread_state
{
  PTHREAD_JOINABLE = 0,
  PTHREAD_DETACHED,
  PTHREAD_EXITED,
  PTHREAD_TERMINATED
};

Can a thread be waken up if it hasnt been blocked?
