Realtime thread in Nim (SCHED_FIFO) in Linux

[cmc]

I'm looking to create a realtime thread in Nim- Linux-only is fine for now.

In C, [according to the LInux 
foundation](https://wiki.linuxfoundation.org/realtime/documentation/howto/applications/application_base),
 creating a realtime thread looks like this (shortened C-like pseudocode):
    
    
    function thread_func(){
    }
    attr = attr_init();
    setstacksize(attr, PTHREAD_STACK_MIN);
    setschedpolicy(attr, SCHED_FIFO);
    setschedparam(attr, priority=80);
    setinheritsched(attr, PTHREAD_EXPLICIT_SCHED)
    pthread_create(thread, attr, thread_func)
    
    
    Run

I know I could just use a pthread with C-like init code, but I wanted to see if 
I can proper Nim threads (at least under linux).

I had a look at the Nim `createThread` code, and for linux it looks just like 
the above, minus the real time attribute.

Before I go ahead and create my own patched `createThread` (or use posix ones- 
ew), is there someone who has already done work in this area? I couldn't find 
anything anywhere. Thanks!
