[boost] [asio] introspecting boost::asio::detail::epoll_reactor::run

Hi all, I am investigating a livelock in a running process inside boost::asio::detail::epoll_reactor::run and I was wondering if someone was in this situation before and may have some tools (gdb scripts?) handy which can be used to get a list of currently pending tasks inside the epoll reactor. Thanks in advance! Best regards, Isidor
