asio and kqueue (2nd trye) (was: RE: (boost::)asio and kqueue problem)

[Hartmut.Brandt at dlr.de]

Hi all,

here is the 2nd try taking into account the comments I received. Since I'm not familiar with the locking in the sockets area I ask somebody with that knowledge to check it before I commit it.

Thanks,
harti

Subject: (boost::)asio and kqueue problem

I am not using boost but I have also encountered this unexpected behavior when calling listen after kevent. Is their any update on the approach to merge filt_soread and filt_solisten?

FYI - MacOS does not have this unexpected behavior. Read events are not "missed" if the listen is done after the kevent EVFILT_READ change is registered.

Thanks,
-Scott
