Thread objects are tracked by the runtime.  If you explicitly delete them, expect a segfault.  I suppose I could use a pimpl approach to avoid this, but it would be a tad tricky (Thread.getThis() for example).  More appropriate is to use a non-shared static dtor to signal thread shutdown, which is basically how OwnerTerminated works anyway.  It's just taken care of for you.
