Check that -- 64K is 16 pages on the i386.  So it's even worse.

I just read a message from Chuck Cranor claiming that ld.so has 7 pages (28K)
of bss assigned to it.  He claims to account for all but 3 pages (12K) of the
16, though, so I'll have to look at his arguments.

7 pages of bss for ld.so is pretty outrageous, is my initial reaction.  What
could it possibly be doing for such a tiny program?
