And the wait is over! Now there is a select function to multiplex 
on read side of a bunch of channels. This also fixes a bug in the 
poll syscall override with multiple events on posix systems

https://github.com/DmitryOlshansky/photon/blob/master/examples/select.d

```d
module examples.select;

import std.range, std.datetime, std.stdio;

import photon;

void main() {
     startloop();
     auto first = channel!(int)(2);
     auto second = channel!(string)(1);
     go({
         delay(500.msecs);
         first.put(0);
         first.put(1);
         delay(500.msecs);
         second.put("ping");
     });
     go({
         foreach ( _; 0..3) {
             select(
                 first, {
                     writefln("Got first %s", first.take(1));
                 },
                 second, {
                     writefln("Got second %s", second.take(1));
                 }
             );
         }
     });
     runFibers();
}
