I am no expert, but I guess if you need to do async programming
on UNIX/Linux userspace, your best is to use POSIX Threads.

Very common misconception. The communication mechanisms between POSIX
threads and Unix I/O are completely alien to each-other: it is not possible
to poll() on a thread condition, nor is it it possible to set up a condition
to be woken by data on a file descriptor. As a result, anybody who tries to
use threads to solve problems of I/O concurrency ends up having to implement
a poll() or equivalent loop in each thread, defeating the purpose.

POSIX threads are good to improve on computation concurrency, but they do
not make I/O concurrency simpler, quite the opposite.

The same might not be true for other kinds of threads.
