Why didn't they mention threads?
Oh gosh, that's interesting. I bet that complicates using using errno. Or is errno somehow copied into a local variable?
errno is in thread-local storage (TLS)
Yes. It is too bad that they didn't use a similar solution for the current working directory. Chdir() is process-wide, not thread local :(
