This commit message still bothers the hell out of me. Please, fix it up
to something more readable like the below, for example:

"pgt_buf_top is an address which cannot be used so we should check
whether the new 'end' is above it. Otherwise, the last BRK page remains
unused.

Fix that check and add a debug printout of every BRK allocation."

Thanks.
