[Chilli] chilli_redir hung on reading from unavailable socket

[Wichert Akkerman]

r345 worked flawlessly for 4 days, but unfortunately showed the same 
symptom today:

read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)
read(12, 0x8e31350, 5)                  = -1 EAGAIN (Resource 
temporarily unavailable)

as you can see the strace is very similar, but has two differences: 
there is no time(NULL) call in between the read() calls, and this is a 
different fd (12, while I was seeing 25 before).
