I've been following this discussion, crossing fingers to someone came
to some conclusion, as this is the biggest show-stopper for Cygwin in
several months.

I've not access to a Win 7, but I would like at least to drop some
ideas to someone with more insight comment on and (hopefully) come to
a solution.

1) If we make a service (let's call it cygconsole, or include it in
cygserver, whatever), with no desktop interaction, whose only purpose
is to AllocConsole()...
1.a) do that console gets created?
1.b) Is it invisible?

2) IF the two answers are true, then
2.a) Do an arbitary process can do an attachconsole to the PID of that service?

IF it is also an YES, we have a framework for an
workaround/alternative implementation! Cool?

(crossing fingers)
