retry:

- list_empty(&thread->todo);
+ if (list_empty(&thread->todo)&& thread->transaction_stack == NULL)
+ wait_for_proc_work = 1;

I think the original looks cleaner (in both cases). Assigning a variable with the result of a boolean expression is perfectly reasonable. Perhaps change the type of the variable to "bool" to make it a bit clearer what's going on.

(It would be a different matter if any of the expression had side-effects.)
