Optimize prev. commit for speed.
1) Don't iterate the loop from the environment array beginning each time,
iterate it under the last place we deactivate instead.
2) Call __rebuild_environ() not on each iteration but once, only at the end
of whole loop (of course, only in case if something is changed).
