I found the bug. It's a bug in the objcache calls to free the thread
structure. objcache_put() is being called with td in the context of
that same td, which is illegal.
What I will have to do is put a one-entry TD cache back in the per-cpu
globaldata so the TD remains valid through cpu_thread_exit().
