[Qemu-devel] tb lock in qemu cpu-exec.c

There is a TB lock in the cpu-exec.c. It is held before a vcpu is
trying to find the next tb it is trying to execute. I am wondering
what this lock is for. Currently, qemu is time multiplexing on a host
cpu to emulate smp. No other vcpu can be running while the tb
lookup/translation is performed.

Thanks

Xin
