It's also worth mentioning, that this was his autoreply :) I am not on vacation, but I am at the end of a long time delay. I am located somewhere on Earth, but as far as responding to email is concerned, I appear to be well outside the solar system. After your message arrives at gnu.org, I will collect it in my next batch of incoming mail, some time within the following 24 hours. I will spend much of the following day reading that batch of mail and will come across your message at some point. If I write a response immediately, it will go out in the next outgoing batch--typically around 24 hours after I collected your message, but occasionally sooner or later than that. Please expect a minimum delay of between 24 and 48 hours in receiving a response to your mail to me. If your message is hard to understand or responding takes real work, the response could take longer. So please wait 48 hours after sending a message before you resend it, remind me about it, or ask if I have received it. If it has been less than 48 hours, the absence of a response from me only means you have not given me time to answer. If you are having a conversation with me, please keep in mind that each message you receive from me is a response to the mail you sent 24 to 48 hours earlier, and when writing it, I probably had not yet downloaded your later mail.
