@richardkchapman - please review.

@richardkchapman - modified so that callThreadTerminationHooks handles the condition based on main thread id.

[richardkchapman]

should be static?

[jakesmith]

agree, have changed.

[richardkchapman]

One minor comment. Also would be worth adding a comment about why this is necessary (i.e. that thread-local objects are destroyed before functions called via atexit )

@ghalliday can you sanity check too

[jakesmith]

made mainThreadIdHelper static and added a comment.

@ghalliday - please review.
