Unlike pthread, Qt is object oriented, and does + not support the calling of a static utility function when the thread + is about to close. In this patch we call the ThreadSpecific::destroy() + utility function from the destructor of ThreadSpecific::Data. Moreover, + since Qt resets all thread local values to 0 before the calling of the + appropriate destructors, we set back the pointer to its original value. + This is necessary because the get() method of the ThreadSpecific + object may be called during the exuction of the destructor. + + * wtf/ThreadSpecific.h: + (WTF::ThreadSpecific::Data::~Data): + (WTF::::~ThreadSpecific): + (WTF::::set): + (WTF::::destroy): + +2009-09-10 Oliver Hunt <oliver@apple.com> + + Reviewed by Geoff Garen. + + Allow anonymous storage inside JSObject + https://bugs.webkit.org/show_bug.cgi?id=29168 + + Add the concept of anonymous slots to Structures so that it is + possible to store references to values that need marking in the + standard JSObject storage buffer.
