OK. Just for you to know that the proposed API is the result of this 
exact work done 10 years ago as the outcome of the european STREAM 
esprit project. The stream IRQ handling API was the result of endless 
discussion among the major european telco teams (alcatel, siemens, Bosh, 
Philips, and even AMD or USL labs) all pushing for their either 
propriatory or favorite RTOS API for IRQ handling. It involved at that 
time at least VRTX, Unixware for the number of driver availiable, pSOS 
and VxWorks. So even if this does not seem to be the case, this API has 
some background behind it. I know for sure one OS where portability is 
was very obvious : ChorusOs... <http://www.jaluna.com>.
