for ( int i = 0; i < 10000000; i++ )
{
x = x + 1;
}
If you had 5 threads executing this code at once, the value of x WOULD NOT end up being 50,000,000. It would in fact vary with each run.

...For those interested in the source, the default recursion limit is set to 1000 hg.python.org/cpython/file/tip/Python/ceval.c#l691 and it can be changed using the API at hg.python.org/cpython/file/tip/Python/sysmodule.c#l643 which in turn sets the limit to the new value at hg.python.org/cpython/file/...
