OPTIM: poll: enable support for POLLRDHUP On Linux since 2.6.17 poll() supports POLLRDHUP to notify of an upcoming hangup after pending data. Making use of it allows us to avoid a useless recv() after short responses on keep-alive connections. Note that we automatically enable the feature once this flag has been met first in a poll() status. Till now it was only enabled on epoll.
