Bug 884239 added a build-time Android version check around the pthread_atfork function definition at the same time as for timer_create, which was subsequently removed. But it turns out the version that documented was wrong: per the comment added in bug 680190, pthread_atfork might have been supported since Android 2.3 (gingerbread, API 9 or 10). That might not be entirely accurate, though, because the bionic repository seems to show it made it to Android 4.0 (ice cream sandwich, API 14 or 15). Either way, that is less than the minimum API version we currently support, which is 16.
