Will always be false for TCG + iothread.  What's wrong with 
qemu_cpu_self(env)?  It appears to do the same, and it would also make 
the whole thread-local storage stuff redundant.

If there are performance problems, you can fix them by using TLS for the 
KVM case and keeping the existing implementation for TCG; at which point 
you can just use __thread because KVM can assume Linux and hence a 
working __thread.
