Cool, it has a man page :) I checked the files/directories mentioned
in the page, and nothing seems to indicate that there is anything that
would allow firefox to increase its priority.
It might not need a special allowance because I have allowed the user
to set a nice level of up to -10 in /etc/security/limits.conf. I
think that doesn't mean that firefox could get real time priority
though --- unless rtkit-daemon is somehow able to set any process that
asks for it to whatever priority the process asks for.
If rtkit-daemon can do that I wonder why the default configuration
is made to open such an enormous security backdoor.
