TOCTOU Poem



What I need to do today,
is to find some gap in time.

A gap in time that no one thought,
a flaw in time that no one caught.

What I need to do today,
is to find some variables.

Variables that shared by threads,
variables that not yet locked.

What I need to do today,
is to find some gap in time.

From the tick of time-of-check,
to the click of time-of-use.
