I had a partially working solution to this using the deallocation stack member of the Win32 Thread Information Block, see https://bugs.webkit.org/show_bug.cgi?id=26276 & http://en.wikipedia.org/wiki/Win32_Thread_Information_Block – but I didn't manage to get this working consistently. Perhaps a Windows expert may be able to build on this.
Bug #26276 would be a great place to be having this discussion, so that anything useful is recorded. cheers, G.
