[Mono-dev] Top again

[Yuriy Solodkyy]

Rafael,

I just submitted a little updated pull request which leaves tpoll_poll
implementation actually unchanged (still buggy as for our porblem).

It fixes our problem in epoll/kqueue implementations and does not created a
deadlock problem in poll-based backend.

See https://github.com/ysw/mono-socket-problem/tree/master/SocketTest on
how to reproduce the problem
See the pull requests on how it happens and how we fix it for epoll.
See: https://github.com/mono/mono/pull/696

Thank you
Yuriy
