Thank you. But about dynamic memory. I don't now about windows disk 
buffers, but when
 colinux write to swap windows must save it blocks to disk from cache 
fast as possible,  if
 colinux have low memory and highly  swap usage, it increase disk usage, 
and highly decrease
 performance of slow laptop disk system for other applications.  I don't 
now much about  windows,
 but why colinux can not use  windows memory manager and windows paging? 
if i can allocate memory for colinux as windows application, i can use 
it on all pc in our lab, and use lot of user pc's free cpu time.

What about mosix port for colinux?
