[okl4-developer] Memory allocation

[Harry Vennik]

It seems to me you'd rather want to have a user-level server thread  
to generate the data. Such stuff generally doesn't belong in the  
microkernel.
In fact one may say that if you think you need to alter the  
microkernel for anything to work, you need to reconsider your idea.  
(The latest public release of OKL4 has still some limitations, so  
changes may be needed sometimes.)
