The description says it is "for strings and bytes" but it should be updated because in fact it works for any kind of objects. regards, GÃ¶ran

There used to be problems with SharedQueue, so Lex Spoon (I think) proposed to use a Monitor based one with tests. We added that to 3.9 at some point, with the idea of testing it. I think SharedQueue2 can be removed, there have been bugfixes included for SharedQueue in the meantime. Marcus
