Hmmm, maybe not.

It doesn't look like a threading thing after a quick glance.  We only thread 1
path, in both 11.2 and trunk:

a.c.193t.dom3:  [4] Registering jump thread: (11, 3) incoming edge;  (3, 5)
joiner (5, 12) normal; 

And it's actually in DOM which has been largely untouched in this release.

Could someone bisect this?
