Superhack multithreading stack error?

It seems to me the multithreading is not working correctly because of the stack manipulations. Do any of you feel the same? For example, try this code on php:
[code]
&\11111111111111!
\000000000 !
[/code]

Actually there should be a space in the very beginning of the second line of code, but it was eaten by the forum, I believe.

It works according to the definition. Don't forget that the memory is shared. The thread 0 has stack pointer pointing further than the thread 1, so thread 0 writes before thread 1 reaches the position and thread 1 rewrites ones by zeros.
