I've noticed a problem, which I think might be a bug. It causes some
grief for me with the Boomer project.
Specifically, when a stream is opened as nonblocking (FNDELAY,
O_NONBLOCK, etc.), I find that I no longer get M_READ notifications,
even when I've asked for them using M_SETOPTS and SO_MREADON.
This causes problems, because I really don't want to start an audio
engine recording until the user application calls read(2). However,
without M_READ notification, I have no way to detect the point at which
the app calls read(2).
Is this behavior a bug? I'm inclined to believe so (after all nothing
in the documentation that I've seen suggests that this special semantic
might exist), but I'd like to know what others think.
