Created an attachment (id=45951)
 --> (https://bugs.webkit.org/attachment.cgi?id=45951)
Patch with test.

Same change, with a test.

See DumRenderTree.mm and WebKitTools/ChangeLog for the description of the test.
Basically, it starts couple of trivial threads that use WTF::currentThread()
method. Without the fix, there are at least 2 ASSERTS on the way of DRT to
completion.
It simulates scenarios when embedders like Safari run threads not created by
WTF that call into JSC/WebKit code which can use currentThread(), or  DRT
running with '--threaded', to name a couple.
