  Log:
  Attempt to make the proper changes here for the proc.h commit:
  
    Make sigaltstack as per-threaded, because per-process sigaltstack state
    is useless for threaded programs, multiple threads can not share same
    stack.
    The alternative signal stack is private for thread, no lock is needed,
    the orignal P_ALTSTACK is now moved into td_pflags and renamed to
    TDP_ALTSTACK.
    For single thread or Linux clone() based threaded program, there is no
    semantic changed, because those programs only have one kernel thread
    in every process.
  
  which left out SVR4 bits.
