  Recently, I consider implementation heritical scheduler on top of the l4 
microkernel, But we meet a problem, the Pistachio handled the interrupt in 
microkernel internal, In that time, I remember a project in TU-Dresden is 
build on top of microkernel, But it`s implementation in the old l4 
interface, just like the Hazelnut that not handled the interrupt (?), The 
suitation is some microkernel abstract the interrupt and some microkernel 
not abstract the interrupt.
  Can we implementation a real time soft mechanism with interrupt 
abstracted microkernel, the real time ipc, feature as:
  interrupt generated then a ipc send to handler and switch to the handler 
at once
