I agree it might be less efficient, but sometimes it is the price to pay for greater generality/simplicity. After all, If I *really* wanted efficiency perhaps I would have written everything in C++.

Anyway, thanks!

n.p.

1. "but should not cause any pratical difficulties" <-- you have a typo in 'pratical' there.
2. What exactly do you mean by "managed" queues in the new addition?

Also, did part #2 of the note come up in other reports? It seemed somewhat trivial (can't hurt though)...

Finally, I don't know whether I'm supposed to close the issue, but its a good solution as far as I'm concerned.

Thanks again!
