Oracle works on Dtrace for Linux (The H)

Oracle is completely indifferent to nurturing a healthy Eco-system of open source projects unrelated to their core strategy. Their behavior towards OpenOffice, Hudson and a long list of other projects is just that: indifference.

The Linux kernel they care about. They want it to flourish, because they _know_ they can't compete with Microsoft alone; if _they_can't be the OS monopolist, the second best option is that nobody is the OS monopolist. That's why they're being good citizens and fixing loads of kernel bugs and working on shiny new features like btrfs within the kernel community. No periodical code drops like some other companies I could mention.

That's why my best guess would be that if something comes of this, the entire kernel space solution will be GPLv2, possibly even the user space component.
