Of course Gnus could be rewritten to do potentially lengthy stuff in the background (and that's what usually happens with such things ... e.g., "M-x man"), but it's probably not easy, and in many cases not even desirable -- when the wait is short, I think it's less confusing for the user for such actions to be synchronous.
There is that.
Another place where threads could help is with complex commands.
At present, concurrent complex command invocations must strictly "stack":
the order of invocation is always the reverse of the order of execution of
commands. This can be especially annoying and confusing when you are
invoking complex commands in two completely unrelated windows or frames.
With threads, you could (conceivably) have multiple, independent recursive
