[Opera-Linux] How'd Opera use so many FDs?

[Daniel Eckl]

Hi Bruce!

No that's all fine. That's the way programs run. They open libraries
and embed them, it opens files where it reads and writes to etc.

But it seems that Kenneths opera opens files to write the cache and
forgets to close them after writing....

So he has LOTS more open files, all mentioning this cache4 path.

Best,
Daniel
