Issue TIMOB-20205: Windows: Use of Thread Local Storage (TLS) for Windows 10
Currently JavaScriptCore uses [Thread Local Storage|https://msdn.microsoft.com/en-us/library/windows/desktop/ms686801%28v=vs.85%29.aspx] functions to handle threading. It has been supported even on Windows Phone as well as Windows Store app, but as of Windows 10 it is not supported and it won't pass the Windows App Certification.
