Yeah, Josh mentioned the same. It would only take another three or four
lines of code to decouple it from TouchSocketLockFiles, and then it's
just a question of how much are you worried about the performance cost of
additional file-open attempts. I think either one-minute or five-minute
intervals would be pretty defensible.
