if you're in prefork, off the top of my head I might set a perl global and
then reset it using a cleanup handler. something like
$My::Foo::seen++;
$r->register_cleanup(sub { undef $My::Foo::seen });
so, again in prefork only, at the start of any request $My::Foo::seen should
be false. all bets are off if you're using threads.
