Realtime capabilities?

[Ben]

Hello world,

some of you have probably heard (or even used) Erlang (www.erlang.org) --- 
a functional programming language which is executed by a virtual machine. 
One interesting property of this VM is guaranteed soft realtime execution 
of the Erlang processes.

My question is whether it is possible to add (soft) realtime capabilities 
to the Python VM with reasonable effort? I'm just curious and not being an 
expert of any of the existing Python implementations I thought some of you 
might have a better understanding of this issue and can comment on this?

Thanks,
Ben.
