It costs some time to create a process, and threads don't have that

On a system that has only ever supported 1:1 threading as default
model, 'process creation' being much slower than 'thread creation'
would be a strong hint at a deficiency in the kernel. But reportedly, the
difference is negligible on Linux, so your assumption should be
wrong. And it is a strawman, except if you constrict yourself to a set
of real-world cases where the reason you try to shoot down actually
was the reason to use threads.

This is a nonsensical reply. Thread creation is in no way analogous to
process creation. Threads are reusable, processes are not.
