-C num is a fancy way of setting PHP_FCGI_CHILDREN=num. spawn-fcgi simply
passes the environment down to php-fcgi and does not care one bit for
*any* PHP_* env. variables (-C is pure convenience).

Have you seen the perl launcher for fcgiwrap on my website? It is
(grossly simplifying) a drop-in replacement for spawn-fcgi and you could
run php-fcgi behind it if you so wished.

I guess you could try reporting it on the PHP bugtracker...

Maybe you haven't exported the variable for the php process to see
(somehow). Anyway, you'd probably see the exact same behaviour with my
primitive launcher.

Which, again, has hardly anything to do with spawn-fcgi. Or Nginx, for
that matter (drifting way off topic).
