net/http: panic: persistConn was already in LRU #18058

What version of Go are you using (
I saw a previous report of this too (in #18061), which is worrying, but in the previous case the poster couldn't answer whether their program was race-free and I spent a fair bit of time reading the relevant code again and couldn't see a way for this to happen.
@zeropool, how easily can you reproduce this? Can you send a complete program that causes the program? If so, and you're unable to run the race detector yourself, I could run your stand-alone reproducer program on a 64-bit host to check for races.
