Perhaps I should have added in case it is relevant, I am not
actually interested in building lists. I eventually want to use
this in a "persistent" version of a red black tree (where if r is
such a tree and we set r1=r.insert(x) then r is unaffected and r1
has the new element inserted - but they share most nodes). This
data structure is to be used in a multithreaded application
searching for a solution to some problem. The current version has
bad performance seemingly due to gc stopping all threads while
freeing unused nodes.
