issues building w/ pinger under freeBSD? about cacheboy HOT 2 OPEN

r13083 - makes it compile again, but its not properly working?

r13084 - make it work again; but the stderr logging isn't being thrown through 
to the debug log. The ipc and 
debug logging changes make it so the ipc code doesn't know about the stderr 
debugging FD.

The real fix is to bind the stderr FD from each ipc connection over to a 
dedicated FD handler which redirects 
everything through the debugging code. This way stuff like syslog logging of 
IPC stuff will work.
