Hello,

I'm saying with my *very* limited knowledge. Please don't hurt me so hard
even if it's totally crappy. ;-)

How about having a dedicated thread or something for the allocation? When
page fault occurs we can wake it up with sufficient information and let
it start to do the work on behalf of the user. Doesn't it make any sense?

Thanks.
