There are a couple of issues with the replay block example:
- It doesn't work correctly for ports other than the default port because
some function calls have missing "port" args or they are set to zero rather
than using the specified port (see attached patch file with changes).
- It can take a very long time to flush the samples. Is there any way
around this? Note that I am using a sample rate of 12.5 MS/s and it takes
several seconds (perhaps up to 10) to flush. I am not certain how
consistent the time is.
