Description Mark Hahnenberg 2014-05-23 19:22:41 PDT

We set a particular flag in the JSLock for a VM when it's being used by WebKit. Some of our clients are tripping up over trying to use a WebKit-based JSContext on multiple threads. We could help them out by logging an error if we ever observe on a thread other than the main thread the use of a VM with a JSLock with the m_hasExclusiveThread field set.
