For the CLH Lock, professor mentioned a node created by a thread and deallocated by another thread would be bad for performance, but didn't mention too many details, I am curious why it is bad for the performance? Is it related to the operating system or how hardware works?

I mean I understand by doing so, the exclusive resource become a shareable resource, but I am just curious what is happening
under the hood with more concrete explanation.
