Forcing to primary is useless, every real-time task starts in primary
mode, regardless of the relevant skin.

There is no reason for rt_queue_read() to move the thread to secondary
mode. You should try running the app over GDB, and inspect the backtrace
when the signal is received; you might discover that some other code
does cause this, or you might discover that we indeed have a bug hiding
somewhere. Posting a simple but complete test code that reproduces the
issue unambiguously would help too.
