Indeed they are,
I'm told that it's standard/common practice to do the close() loop
before spawning the main daemon though. 
0 is Std_in, 1 is std_out and 2 is std_err.

So squid on cygwin is stackdumping when close(2) is called. I have
worked around this in squid now, so it's certainly not urgent (for me),
but the behaviour is different than on most un*xes.

Call me crazy, but aren't fd's 0,1 and 2 == stdin, stdout, stderr (in
some permutation)?
