Is there existing practice for unregistering pthread_atfork() callbacks?
Also, should we add the ability to unregister an atexit() callback?

In my opinion adding the latter would be a real enhancement.
POSIX has dlopen(3) *and* dlclose(3), but no standardized way to
give such dynamic code the possibility to perform proper
finalization. And of course there can also be code that is active
only for a short time and maybe never thereafter. Could be an
object, however.
