-    <braunr> yes, we have integer overflows on resident_page_count, but
-      luckily, the member is rarely used
-
-See also [[gnumach_vm_object_resident_page_count]].

-    <elmig> this is declared as int on vm_object.h
-    <elmig> and as it as counter it's always positive
-    <braunr> yes it should be unsigned
-    <elmig> ok
-    <braunr> but leave it as it is for consistency with the rest
-    <elmig> i send patch :)
-    <braunr> please no
-    <braunr> unless you've fully determined the side effects
-    <elmig> i've grepped the vars and saw only comparisons > and = 0
-    <elmig> never less than 0
-    <braunr> > 0 is the same
-    <braunr> well
-    <braunr> > not, but >= would be a problem
-    <elmig> http://paste.debian.net/plain/8527
-    <elmig> asctually no >=0
-    <braunr> still, i don't want to change that unless it's strictly necessary
-    <braunr> hum, you're grepping ref_count, not resident_page_count
-    <elmig> i did both
-    <elmig> on resident_page_count theres resident_page_count >= 0
-    <elmig> = 0, == 0
-    <braunr> this isn't the only possible issue
-    <braunr> anyway
-    <braunr> for now there is no reason to change anything unless you do a full
-      review
-    <elmig> only place i see resdent_page_count and page_count being decreased
-      it's on vm/vm_resident.c
-    <elmig> vm_page_remove() and vm_page_replace()
