Agreed.

You maybe .. what was your rest time before the flight .. how much time you had flying
Remember that captain Dubois had many many hours (days) for rest in Rio and he was not from looong time on flying AF447 on the return segment
It doesn't much rest he (or I for that matter) was rostered to have had. In an ideal world (the sort of world the regulators live in) after a multiday slip you will be well rested, but we all know that sometimes you're not at all rested. You've maybe had bad sleep, had your sleep disturbed by the party out by the hotel pool or the couple in the next room
.
In heavy crew ops as a captain, IMHO, you are entitled to think that your colleagues on the flight deck can action, at the very least, the initial items a non-normal checklist, and contain a problem long enough for you to get dressed and return to the flight deck. If (note, I say "if") that wasn't the case on AF447 then the problem lies with AF's procedures, training and checking of junior crewmembers, not with captain Dubois sleeping arrangements.
