OK, having been bitten by running out of FDs so many times in Opera 9.6X
(the 10.X betas still dump core far too often - I'll be glad when the new
crash-dump facility is ready for Linux!), and its resulting effects (not
being able to save state on exit, dialog boxes coming up blank 'cause
it can't open font files, etc.) I decided to solve the problem by
bumping up the per-user open-file limit on Linux:

I added this line to /etc/security/limits.conf :

kenny		-	nofile		10240

... giving me 10K open FDs, so when Opera 9.64 needs an ridiculous
amount of open files, like this:

... it can get 'em. But *certainly* someone's gotta know why there's
2048 cache files alone open, right?!
