Yes, definitively. Even without concurrent access, it very rapidly turns 
the code into an unscrutable mess.

Mostly, yes.

As usual, this is not a hard rule but a guideline. But I use as few 
globals as possible, and almost all of them are read-only. The very few 
exceptions are dirty hacks, mostly called at init time.
