Interesting... 

Apparently, sys.function() is still a promise after the  function has
been called (and the promise obviously forced).
Minimal example of same effect:

> f<-function()sys.function()
> f()
function()sys.function()
> g<-delay(f)
> g()
<promise: 0x8b248b4>
> g<-g
> g()
function()sys.function()
