Entertainingly, changing the Buffer in Deque.h to default to inlineCapacity=1 instead of 0 (and rebuilding WebKit) just causes all loads to hang.  (I changed all Deque's to use inlineCapacity=1 on their Buffer to see if that would fix my malloc trouble, w/o me having to plumb inlineCapacity support all the way through Deque out to where SegmentedString could specify an inlineCapacity.)

WebKit seems to sit there idle.  The only thread with anything interesting on it, is the IconDatabase thread waiting to sync to the main.  All others are just sitting in the runloop.

I suspect that some use of a Deque'd object has a side effect of its empty constructor or some such.
