Well the deadproc list was using the p_hash member - which no longer exists.
Since processes only sit on the deadprocs list for a very short time,
changing it for FIFO to LIFO isn't an issue.
A LIFO list doesn't need any macros...

For a readability point of view I find the 'hand-coded pointer manipulation'
better than the list macros.
