Hi, we know that ExecutionQueue is worked as a batching mechanism,say we
sumbit some tasks and the "execute" runs in one bthread,after processing all
the tasks in "iter",it exits the bthread and wait for a next batch tasks,and
run again(and it allow t run the tasks "in place",while it still has a
"start-process-exit" lift cycle).
Nowdays,polling is popular in area such as intergrating with SPDK,I'd like
to write code like following,making the "execute" always looping in one
bthread(maybe this idea conflict with bthread design target:it won't do a long
runing task while not allow a re-scheduling?):
```
int execute(void *meta, bthread::IteratorTask<std::string> &iter) {
while (iter.is_queue_stopped() == false) {
for (;iter; ++iter) {
// submit IO task with spdk
}
// submition finished,and I'd like to polling spdk result
// spdk polling
}
return 0;
}
```
while in current ExecutionQueue implemetation,I have to start a another
bthread doing polling and send fake task to the ExecutionQueue to trigger SPDK
polling thing,is this the better way to use ExectionQueue?
