I think it's important to define what you mean when you write,
"thread condition."  What, exactly, is that?  Perhaps you mean
a condition variable?

Yes, of course that is what “thread condition” means in the context of a
discussion about POSIX threads.

If so, that's true, but I fail to see
the relevance: people write multithreaded code that does IO in
multiple all the time; there are some techniques that are common
for this (Scott alluded to the so-called "pipe trick", due to
Bernstein) and some that are less common.

Yes: there are some techniques that are common to implement I/O concurrency
and that work in the context of threads. You are arguing my point for me:
the threads did not make implementing the I/O concurrency simpler; quite the
opposite it they made them harder, as proven by the fact that “techniques”
had to be deployed.

POSIX threads do not make I/O concurrency easier, they are not made for
that, they are for performance.
