ghc_ticker loops if permission denied on timerfd
Using stack with lts-11.6 to compile a cgi programme, I got something that runs OK from the command line, but which goes into a busy loop when run from httpd. This is caused by selinux preventing read on the timer. Changing the selunix permissions solves the problems, but ghc-ticker ought to check whether the read succeeded and not try again if it fails.
