Hmm. It very well might be the rename detection allocating a lot of
memory to do inexact rename detection. It does try to limit the amount
of work, but based on number of files. So if you have a lot of huge
files, that might be fooling it.

Try setting merge.renamelimit to something small (but not '0', which
means "no limit").
