* This function depends on "type": if SAND_WORKER, we set fd1 to be the

* it's the FastCGI control connection (fdfiled and fdaccept should be

* If not SAND_WORKER, we're the control process in a FastCGI context:
|
|
* fd1 is the control connection; fd2 is -1; fdaccept, if not -1, is the
|
|
* old-style FastCGI socket; fdfiled, if not -1, is the new-style
|
