Maybe it should be renamed to 'query uncapability' ?  If you have a
bigger capability number (i.e. more capabilities :), you should be
faster.  

It's also interesting that Linux seems to give you way more info about
HW with /proc/sysinfo than is easily obtainable from VM.

In all seriousness, lower=faster is no more a restricting factor than =

higher=faster.  In either methodology you're going to run out of bits a=
nd whether it's at the high end (overflow) or the low end (underflow) is
irrelevant.  When the condition approaches you either need to add more =

bits (to the left or right as appropriate), adjust the range of values =

generated, or switch to a floating point representation (which only
postpones using the first two options).  The main disadvantage of the
current lower=faster using integers is the increasing rate of loss of =

precision as zero is approached due to truncating/rounding of data.
