"I managed to find a solution to this. I create a ram filesystem (tmpfs)  
and dump fixed length files there with gnuradio. I then move the files  
when  
they are complete to a persistent drive using another script. I don’t  
know  
why I didn’t think of this before.

Can you elaborate on this please? What do you mean by “dump fixed length  
files there with gnuradio”? Do you mean you use a file sink (connected  
to a  
RAM disk) with a set number of samples?
