putenv() does the same thing as setenv() except that it takes a single
string argument where the name and value are separated by "=", not a
Schemely protocol.

environ is a variable, not a function.  This means that the only
practical semantics is that environ is shared among threads.  Having
environ be a procedure would allow each thread to have a separate
environment.
