I am doing this:

def remove_current_tasklet():
  cur = stackless.getcurrent()
  tmp = cur.setatomic(1)
  try:
    x=stackless.tasklet(lambda x: x.remove())(cur)
    x.setatomic(1)
    x.run()
  finally:
    cur.setatomic(tmp)

Basically create another tasklet to remove the current one -- the
atomic stuff just makes sure that the yield is direct (i.e. nothing
else can intervene).  This is necessary since I am pre-emptively
scheduling -- it is simpler in the case of voluntary scheduling:

  stackless.tasklet(lambda x: x.remove())(stackless.getcurrent()).run()
