Just a note : worst-case scenario might be that the first thread
finishes reading before the last has even begun its work. Also tracking
which thread "eats" the "leftmost" elements of the stream is problematic
since the stream can't know who is reading him ... Moreover, one of the
thread could store or "give" the tail of the stream to some long-living
entity (mutable store ? some distributed entity ? dont know exactly).
Then, better leave it the the GC.

(sorry for the random and fuzzy thoughts).
