[Chilli] redir in busy-loop

[Wichert Akkerman]

With svn revision 331 we noticed that after 2.5 days the redirect 
process got stuck in a busy loop and was no longer processing requests. 
An strace showed this:

read(12, 0x92dc418, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x92dc418, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x92dc418, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x92dc418, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)

repeated at high rate. I had to send a KILL signal to the redir process 
to stop it. I was half hoping that chilli would notice the redir process 
going away and restart it, but alas that was not so and I had to restart 
chilli.

Wichert.
