Who said anything about disabling system resource tracking? "track all
closes" means to call the devsw d_close function for *each* close, not just
for the "last close" as 99% of our drivers expect... If we suddenly caused
d_close() to be called on every close() syscall, then existing drivers break
because they are used to freeing everything and cleaning up when the close
function is called.
