Says who? cpu_interrupt() calls tcg_handle_interrupt()
which calls cpu_unlink_tb() which makes changes to the
TB datastructure with no kind of locking at all.

I'm actually working on a patchset which fixes this
(by having every TCG TB check the exit_request flag at
the start and exit if set, so we can throw out cpu_unlink_tb()
entirely), but as of right now the codebase is definitely
not threadsafe.
