Ugh, WK2 won't build, forgot a WebCore project file change to export a new header.

Ummm... thanks EFL?

Last 500 characters of output:

Didn't see this on the Mac with the LevelDB build enabled...

Might have been my mistake.  Uploading new patch to check.

Typo, LevelDB

This would look slightly more straightforward like so:
Deque<OwnPtr<IDBPendingOpenCall>> pendingOpenCalls = std::move(m_pendingOpenCalls);

Hm, I wonder if we couldn't even do this:
auto pendingOpenCalls = std::move(m_pendingOpenCalls);

I'll skip on trying to make either of these changes, as both result in:

/Volumes/Data/build/Debug/usr/local/include/wtf/Vector.h:141:32: Call to implicitly-deleted copy constructor of 'WTF::OwnPtr<WebCore::IDBPendingOpenCall>'
