This is/was about hpux.  One can safely assume almost no code is using
static linking.  And if it is not used having two competing
implementations can be really bad.

In any case, I assume that today most systems have the functionality of
unregistering handlers in objects which are dynamically unloaded.  This
cannot work if an alternate atexit implementation is used.  The result
will be crashes where the code used to work before.


Saying that it _could_ work in a few boundary cases (like static
linking) doesn't justify introducing changes which can render perfectly
working code into crashing code.
