Ok. There is no use case that pops to mind. Got one? I think that if
i had the need, i'd (re-)order it [t]'er-wise. To be a little risky
and "fresh"; I think using [delay 0] like that is "spaghetti coding".One use is the to avoid suicides. Using [delay 0] (ah, brackets again) was used to work around a crash when closing the gemwin from gemkeyboard. Another suidice is attached.
Then if you have long-running [until]s that generate stack-overflows, you can work around this by dividing long computations into smaaller chunks with some [delay]s as well. Of course working around stack overflows this way can be even more dangerous, as is illustrated with the [pipe] example in attachement as well. [pipe] also act as an endpoint to depth first travesal just like [delay].

i once also had a use for [delay 0]. i had to open [spigot] to pass an unkown number of messages, that all were sent in 0 logical time. since i didn't know the number of messages beforehand, i could use [delay 0] to close the [spigot] again, after all messages have passed. this sounds like a bit a wierd example, but somehow it made sense in that case.
