Changes for version 1.00
- eliminate trailing newlines from trace messages to avoid PID spam in the trace
- use the Time::HiRes NVTime entry if available instead of calling gettimeofday().
- methods check the loop has been initialized, since some loading mechanisms load two loops and initialize only one. https://rt.cpan.org/Ticket/Display.html?id=55064
- POE::XS::Loop::Poll - an XS implementation of POE::Loop, using poll(2).
