 Log:
 File descriptor cleanup stage 2, remove the separate arrays for file
 pointers, fileflags, and allocation counts and replace the mess with a
 single structural array.  Also revamp the code that checks whether the
 file descriptor array is built-in or allocated.
can anybody enlighten me why this was done in the first place?
this way it's much clearer anyways


But it is also slower because the amount of data which has to be copied when
the array is extended is now doubled. (pointer vs. struct fdnode)

	Can't we not just make them all allocated?  I am assuming here that
	allocator descriptor arrays is "pointer" and the other is "fdnode",
	according to your interpretation, right?
