Would it change the perception if I say I forgot to mention that the
only case I accept even the blocking I/O is in a thread dedicated to
reading/writing the data? I guess, it may be considered as anvanced
asynchronous I/O - I can process the data I read/write in the same
thread I read/write it.

Generally, what is it about, I guess, is half-sync/half-async design
pattern described in the document reference to which was posted by Alex
Oren (Design patterns for concurrent, parallel and distributed systems)
- THANKS, Alex, it was great.

Other thought is - how often do you need the *DUMB* asynchronous I/O - I
mean, without a possibilty to process the data, as (if I remember it
right) it happens in WinNT API? I've been working with that API for
quite a while and honestly don't remember myself actively using it.
