Python script changes in the patch seem unrelated.

I think that "m_assertionFlagsAreForeground" would be a more descriptive name for this.

Or perhaps we can ask m_assertion about whether it's taken?

I'd use a const, not a #define.

Typo: aquire.

This leaks, please use adoptNS().

…and constants should be named like local variables, starting with a lowercase letter.
