Redis Redis 6 multi-thread high CPU usage -- "tight loop" like code

In the code of netwroking.c there are some place to use "while(1)" loop to wait for some condition.

for examlpe in function IOThreadMain there are such code. while(1) { /* Wait for start */ for (int j = 0; j < 1000000; j++) { if (io_threads_pending[id] != 0) break; }

Maybe these code will run like "tight loop".

Do we have have special perpose to do this?

Or we need further plan to enhance this ?
