The above script addresses a slightly different, but important problem. 
  A problem can come up in multiple initialization in some cases.

My variation:

local inUse = false

on libraryStack
   if the target is me then
     if not inUse then
       -- first init
     else
       -- init for other than first
     end if
   else
     pass libraryStack
   end if
   put true into inUse
end libraryStack
