Deepa,
it seems that we both are saying the same things again and again, and we
simply can't understand each other.
I'll try to write another email to restart this discussion. Tomorrow, somehow
I can't wake up today.
And let me repeat, of course I can be wrong. IOW, it is not that I am trying
to blame you for all this confusion.

I agree that "the lost -EINTR" above was not clear. I'll try to clarify
what I think is not OK.
Oleg.
