Must be the longest meeting ever. Is there really that much to talk about?
In 2004-05 they had marathon sessions to get it done. Is this the beginning of that? Doubt it, but still. Here's Wiki's article on it.
Bolstered by the thought of losing yet another season to a labor dispute, the sides began meeting again in June, with many pundits believing the lockout would end on July 4, 2005. That date eventually came and went, but sources were reporting to media that marathon sessions were taking place. Indeed, the sides met again for ten consecutive days (July 4–13), and a deal was reached "in principle" (meaning the sides have agreed, but nothing is signed) on July 13. According to reports, the July 12 session lasted through the night and until 06:00 on July 13, at which point the talks broke off for five hours, and resumed in time to complete the deal.
