Hell RTers

I found the following paragraph at 
http://www.mysreenu.com/linux_software_design.html.
Would someone please tell me whether the last sentence is correct. It was my 
understanding that anything running under Linux could be prempted by a RT 
scheduled task under RTLinux.

Thanks,
Daniel

"Even with RTLinux/RTAI, it is generally the case that a real-time
application will have tasks executing within user space. The issue then
becomes the reliability of their performance. The behavior of all userspace 
programs, including daemons, may be important. In particular, if any user 
task other than your time-critical real-time task is making system calls, 
then that may delay your task."
