Subject: Re: vmlinuz-3.12.13-rt21 freezed by application

Same effect with vmlinuz-3.12.14-rt23 even with WindowMaker.

The fan turns on on no reaction of the OS without any special realtime
privileges. The threads run at priority 0 and can't switch to TTY[0-6].

It's a recent mac book pro output of `lspci -v` attached.

I have programmed a thread wrapper AgsThread with glib-object using
pthreads. I'm syncing a tree and having a thread pool which adds threads
to the tree at runtime.

Finally my question, what is the state of realtime kernel thread safety?
My application runs more or less stable with default debian kernel
configuration. But getting real bad performance.
