You are right. Which means the only way I know of to handle the signal synchronously is the pipe() trick that I used in the patch. I guess is doesn't matter that it isn't portable as signal_reload() only happens under Unix anyway, so the solution to handling it only has to work under Unix. A couple of judicious #ifdef's should fix the portability problem. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
