[Haskell-cafe] Thread priority?

Is there any interest or movement in developing thread priority or any 
other realtime support in Haskell?

Right now, if I have tasks that need to be responsive in real time, even 
if the realtime needs are very soft, it seems that the only option is to 
try to ensure that at least one hardware thread is kept clear of any other 

To be very useful to me, thread priority would not need to come with very 
strict guarantees, but there would need to be a way to make sure that 
`par` sparks and DPH inherit the priority of the sparking thread.

In part I ask because I'm working on a small library to support a degree 
of cooperative task prioritization.
