thread not detaching

[jdksh 0]

Im trying to control a nuclearcraft reactor with the rc api and threading, but when i run it freezes the whole pc

function start()
 local thread = require("thread")
 t = thread.create(function()
  local component = require("component")
  local r = component.nc_fusion_reactor
  while(true) do
   if(r.getEfficiency() < 100) then
    r.activate()
   else
    r.deactivate()
   end
  end
 end):detach()
end

function stop()
 t:kill()
end

You need to yield the thread, use os.sleep function in while loop block.
