Good question. I know that there are about 7K pattern variables
and about 900 pattern rules. There are quite a few files involved,
but I wouldn't say more than a thousand or two. None of that really
explains the turnover or 45M of reachable memory at the end.

[BTW, the reason there are 7K pattern variables is because every
 definition is added to the list. For example, if I have:

 %.o: CFLAGS := -g
 %.o: CFLAGS := -g
 %.o: CFLAGS := -g

 All three assignments will end up in the list. I wonder if we can
 be smarter here?]

Here is the log. I also added --show-reachable=yes:

Ok, I will work on this. Which GNU/Linux distribution are you using?
