I'm not a specialist. Although I remember several prop= osals=C2=A0
specifying algorithms and objects to do fork/join.
I thought that some of these were added in the recent parallel algorithm = TS
but I cahn't find them there.

Actually, the proposal is about=C2=A0parallel computing and= =C2=A0fork/join=C2=A0as basic constructs of task parallelism.=C2=A0<= /div>
I use a queue, but probably you know a better data structure that= fit there.
And by the way, it is only thread safe for the produc= er.
