If the guest attempts to execute from unreadable memory, this will cause us to longjmp back to the main loop from inside the target frontend decoder. For linux-user mode, this means we will still hold the tb_ctx.tb_lock, and will deadlock when we try to start executing code again. Unlock the lock in the return-from-longjmp code path to avoid this.
