_lwp_suspend() suspends execution of the LWP specified
  by lwp. Once an LWP is suspended, subsequent calls to
  _lwp_suspend() have no effect. The only way to resume
  execution of a suspended LWP is via _lwp_continue().
_lwp_continue() resumes execution of the
    LWP specified by lwp. Once an LWP is resumed,
    subsequent calls to _lwp_continue() have no
  effect.
_lwp_continue() and
  _lwp_suspend() functions return the value 0 if
  successful; otherwise the value -1 is returned and the global variable
  errno is set to indicate the error.
_lwp_suspend() and
  _lwp_continue() will fail if:
