--- Comment #10 from OndrejBilka <ondra at iuuk dot mff.cuni.cz> 2013-05-20 15:12:23 UTC ---
It is valid corner case so it will be open until resolved.

Rich Allocation happen to be 65536 bytes with 4096 alignment.
This is not pathologic case as when you allocate 65536+4096 bytes and pick
aligned address a modified bound mentioned should hold.

The bound says that we must not allocate more than twice usable memory but
usable memory is taken as maximum over program history. 

With alignment this example factor should be less than 2*(65536+4096)/65536
