Clearly you have neither clue about real time nor about operating systems in general.
Solaris, some BSDs and MacOSX use interrupt threads. Where exactly is the relation to realtime?
The concept of interrupt threads is nothing which is in any way related to real time. It is a well known and pretty old concept in operating system design.
The fact that real time operating systems benefit from interrupt threads is a totally different topic.
