Message::Passing::Filter::Delay - Delay messages for some time.
This filter passes all incoming messages through with no changes, however not immediately - they are delayed .
You would normally never want to use this, but it can be useful for testing occasionally, or avoiding race conditions.
Floating point number, indicating how many seconds to delay messages for.
Sets up a timed callback in the event loop, which passes the message to the output (and deletes itself) once the timeout has expired
