But I think the page size problem with brk() is real and can be fixed
quite easily.  If I understood correctly, the problem is that doing
something along the lines of:

	x = ALIGN_TO_4K(sbrk(8192));
	memset(x, 0xff, 4096);
	brk(x);
	brk(x+4096);	

might preserve the contents of the page at X on under the ia32
subsystem of ia64 when in fact it should be cleared to zero.

Would you be able/interested into looking into this?
