Title: Use timerfd if available

The timerfd interface is a Linux-specific set of functions that present
POSIX timers as file descriptors (hence the fd) rather than signals thus
avoiding all that tedious messing about with signal handlers.
It was first implemented in GNU libc 2.8 and kernel 2.6.25.
