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?
