I already sent a fix for this to Alan yesterday, but it seems it was too late
or got lost.
Another question: 4.4.BSD always signal writable in select when an error occurs
on a socket. Should Linux do this too?
Here is the fix again:

P.S.: I would appreciate any benchmark data that test these two options,
especially on bigger squids. If anyone is willing to do this please contact
me.
