When working with threads, try to keep the number of global variables minimal

Why? While that's good advice in general — it's easier to make sure that local variables are in the proper state than it is for global variables — I don't see why it's important for threads specifically. I can see this being an issue for *shared* variables (since their access needs be controlled by locks), but other package, lexical, global and local variables are per-thread by default.
