In env_destroy(), it is a bad idea to env_swap(self, 0) to switch
back to the original environ unconditionally.  The setting of the
variable to save the previous environ is conditional; it happens when
ENV.e_committed is set.  Therefore, don't try to swap the env back
unless the previous env has been initialized.
