Default Real Time OS

As a few of you know, i've got a new job doing some heavy work with QNX ( and unfortunately linux ).

It seems that the rising cost of QNX is pushing us towards RTLinux. Now, I know linux in general is a complete mess of modules held together with rubber bands and it seems RTLinux is no different.

Is RTLinux a true RTOS ?
I've done some googling and seen a bit of talk about RTFreeBSD but it seems to be a kind of emulated RTOS.

I'd personally pay the extra and stay with QNX. I've learnt a lot about it and i really like what it can do and i just don't think linux is a good move.


Any input?

Here is a relatively old paper about RT/Quick-response.
http://news.cnet.com/Novell-to-launc...&tag=nefd.lede
Since then, in the financial world where money is (... err) lost by black-box trading (r-quanted algorythms) the response time now is in th order of nano-seconds.
In order to keep transmission delays as short as possible, the brokers and the main traders now have their trading boxes at the premises of the exchanges themselves.

Question: what is real-time? Be specific, milli-, micro-, nano- ?
