Not that I heard of.

I work around this problem by porting Erlang to RTEMS which is a hard 
realtime OS.
So one can do all hard realtime stuff in C, C++ or fwiw even Ada and 
run it at a higher prio than the Erlang VM

For more info: http://www.grisp.org

Even more info will be up soon, also with adding RSS to the site to 
make tracking it easier.

I could imagine some subset of Erlang along FRP lines being compiled 
specially being able to also write hard realtime tasks without C but 
thats just pipedreams at the moment.

But often the hard realtime stuff in systems is quite small so keeping 
just the hard realtime stuff in C and do as much as possible in Erlang 
on a Grisp system is very feasible.
