Fair enough. I am asking you to get something into 7.2 for practical
reasons. Sooner people will get something, sooner someone will uncover
problems is there are any. That would allow to have reasonable confidence by
the time 7.3 rolled out.

Of course there are betas for such purpose, but people prefer to work with
releases, so I simply want it to have larger exposure. I also want clearer
test case - forcing people to use [potentially unstable] alphas/betas on
QNX6 would distort the picture - if there will be problems it won't be very
clear whether they are related to port or to the base code.

You can mark QNX6 support as 'experimental' if that will help anything.
