In the old implementation, we used the strategy of fork+mutate environ+execvp and we got the traditional shell script semantics from our use of execvp. Since environ is now a global shared-with-parent variable, we can't mutate it any more, therefore can't use execvp, and must implement the missing execvpe ourselves.

Now, strictly speaking, execvp's traditional shell script semantics is an unspecified implementation detail of execvp; on other Unix platforms we might not need this. We can leave this to, e.g. the BSD porters reading this, to add some #ifdefs. Ok, got you. (It would also be good if you ran the updated tests on Solaris with the old implementation to confirm my understanding)

I'm just building it now, and will run the test then.

Thanks, Michael.
