=head1 NAME
Message::Passing::Filter::Delay - Delay messages for some time.
=head1 DESCRIPTION
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.
=head1 ATTRIBUTES
=head2 delay_for
Floating point number, indicating how many seconds to delay messages for.
=head1 METHODS
=head2 consume ($msg)
Sets up a timed callback in the event loop, which passes the message
to the output (and deletes itself) once the timeout has expired
=head1 SPONSORSHIP
