The user thread doesn't. The IO thread does, if you wish to do IO.
And you can easily dispense with the sigio emulation thread.
Furthermore is the actual kernel process multi threaded?
It does what amounts to user-level threads - i.e. there are multiple
execution contexts in it, implemented with setjmp/longjmp, but that's
not visible from the outside.
Thank you, that was all really helpful.
