If you're referring to the delay between sending an email and seeing
it on the list -- this is a result of the Brown mail server (where the
mailing list is hosted) doing "greylisting".  This basically means
that sometimes emails get delayed for a while.

[Greylisting is a method that is used against spam: if the server
doesn't "know you", it will reject your email in a way that makes
proper mail servers retry sending the message.  The idea is that
spammers use servers in a way that makes it impractical for their
servers to resend email, so the email will be dropped.  Once the
graylisting server sees a few emails from you, it remembers you and
will stop doing that delay.]
