timerfd can be fairly easily replaced with a socketpair, where one socket is used in the poll/select and the other is used to signal activation. To wake up the poll/select, write a character into the signal socket. You will need to be sure to read the characters out of the select socket to make sure you don't get a full buffer and back-pressure.
