[reSIProcate] FdPollGrp::Create ----- FdPollImpFdSet / FdPollImplPoll

[许波]

Hi, everyone
When FdPollGrp::Create   return new FdPollImplFdSet(),  it can't open more than 60 sockets.
When FdPollGrp::Create   return new FdPollImplPoll(), it looks like better.
 
My application is a B2BUA,  the media relay use the class MediaRelay in ichat-gw. But the MediaRelay uses the  buildFdSet(FdSet& fdset).
 
How can I change the MediaRelay to use FdPollImplPoll() ?
 
Looking forward to your reply.
