What system has such an unfair scheduler?

A "fair" Scheduler only can be fair if time slices are to be managed. If
you set a thread to a "realtime priority" (OK, you need to be root to be
allowed to do that :) ) it's priority is above all the normal processes.
That  is quite normal if you do embedded Linux systems.

It's a non-issue. If you set a thread realtime you know what you are doing and can take care you give up the CPU when feasible, or you simply don't enter mutuxes shared with non-realtime threads.

Of course if there is a simple fix...
