Adrian von Bidder writes about retty, a tool to make processes reattach to your terminal. While useful, it seems mostly like a limited version of cryopid which seems even more insane and crackful, but quite cool nevertheless. I have not had a chance to actually try cryopid yet though, so if any of you have, please blog about your experiences with it. Oh, and please package it, somebody.
