Agreed.  There has to be a really good reason to sacrifice the support
for these environments.  Yes, atexit won't perform 100% correct, but
at least it works in the main executable which is all you can do with
these platforms.

HJ, why should we care whether atexit takes a handful more cycles to
execute?  What other reasons are there?
