I have to disagree with you with regards to write(). The write(2) man page is deceptively simple, check out open(2), specifically the NOTES section. I count 12 occurrences of the string "NFS".

My favorite part of the whole man page is the Linus quote:

    "The  thing  that  has always disturbed me about O_DIRECT is that the whole interface is
    just stupid, and was probably designed by a deranged monkey on  some  serious  mind-con-
    trolling substances." -- Linus

But thats not a language failing. A language that actually prevents you from writing complicated interfaces is probably entirely unsuitable for... almost anything.
