This small type with its enormous effect I've mentioned a hour ago or so :)
BTW: Rik? I've a simple suggestion for the calculation of the number of
free pages. After the last kernel driver has done its allocation
it would be usefull to remember the number of free pages with
a global variable num_availpages and use this one instead of
num_physpages for the most memory management operations.
This would give a better protection for systems with less amount of
physical ram to be out of the choosen limits for the VM subsystem.
