The site's in French, but FF numbers are the lower in the UK than anywhere else in Europe -- and according to this report, it actually shrunk this fall. (Search for "Royaume-Uni" for the UK's numbers).
Last time I checked, IE's still number one in the UK, and its share seems to be growing. Anyone know why?
And yeah, I know FF isn't Linux or OO -- but its IS free, and it IS open source. And IMHO, its MUCH more accessible for the laypeople than Linux or OO.
Now, if we could only be more like the Aussies . . . .
Yeah, I guess I stuck my foot in my mouth, and botched my terminology.
Technically speaking, QNX does use virtual memory -- however, it doesn't support virtual paging (if I understand it correctly). So pages can't be swapped into and out of memory, and all apps must be memory resident (as you've pointed out).
I believe there are add-ons (potentially third party?) implemented as servers which will support swapping to disk. But these add-ons jeopardize the real-time performance of the microkernel.
So, if I can correct myself, I do believe that supporting virtual pages in secondary storage and being real-time are probably mutually exclusive conditions.
I believe that one of the ways QNX is able to make real-time guarantees is by not using virtual memory. All applications run in memory -- so you don't have to worry about the additional overhead of swapping.
What I'm saying is that having virtual memory and offer real-time performance guarantees are kind of mutually exclusive conditions, and both probably can't exist together in the main kernel.
Here's the chronological order in which browsers (and authoring tools) passed Acid2 (I'm only counting public releases, not nightly builds):
1. Safari
2. Konqueror (except for scrollbars, lol)
3. Prince
4. Shiira
5. Konqueror (with scrollbars)
6. Opera
7. iCab
Firefox's Acid2 compliant branch has been merged into the trunk. Firefox 3 will likely be Acid2 compliant.

OMG . . . Maybe I'M really one of Twitter's sock puppets? Do I really exist?

Since when is SELinux a distro?

Feel free to correct me if you disagree.

Just my 2 cents.
