The required components are now available, and are
being provided
by a few leading-edge distributions. Had you installed Ubuntu Dapper
Drake (which is not yet officially released), you would not have seen
any problem. They chose to include the PAM patches and authorize
all users to start realtime threads be default. That is a reasonable
choice for them (given their goals), but would not be appropriate for
most other distributions.
I thought a realtime-scheduling kernel gives well-defined portions of time and
system resources to processes. Why does that mean userland could dos the
kernel? Is there no kernel watchdog that would kick out processes with
excessive demands? Does the kernel not keep a book for it's own needs?
