Well, it also happens for me when a process is started up from an NT service
(that is not a Cygwin service) which has no bearing on a command shell, or
actually any NT application (even if while the application was started from
a shell, the process it is creating will have no interaction with that
shell)  (That might be synonymous with what you mean by "command shell" I'm
not sure).

Oops, I think I mis-stated - I meant to say is started as a child process
(but my Unix-based brain optimized that phrase with "fork()").  I haven't
tested all cases, but the actual problems I was running into did involve a
parent process (not interactive) that was not Cygwin-based.

I do believe you are correct in the behavior under fork() which was actually
part of the confusing part when I tried to diagnose this originally (which
led to my first note to this list which led off onto a tangent on open
source :-)) - I had thought it was the internally forked child but it was
actually the original stdin/stdout .
