If you mean that it takes a second before the message appears, that is on
purpose. The message will be displayed when Emacs has been idle for 2
seconds. Probably I should make that 1 second. I could inform the user
straight away but I was thinking that the user would miss the message then.
I'm also thinking if I should "queue up" all the messages, if there are
more than one, and show all when the user is idle. Perhaps, if more than
one message has been queued up, I should recommend the user to run M-x
absug-report to show them all?
