If I change my fuzzer command sequence from "btrfs" to "ext4", eg.:
$> mkdir /mnt/ramdisk/ext4; truncate -s 97M /mnt/ramdisk/ext4.fs; /sbin/mkfs.ext4 /mnt/ramdisk/ext4.fs; sudo su -c "mount /mnt/ramdisk/ext4.fs /mnt/ramdisk/ext4; chmod 777 /mnt/ramdisk/ext4"
and then run trinity :
$> D=/mnt/ramdisk/ext4; while [[ : ]]; do cd ~; sudo rm -rf $D/t3 && mkdir $D/t3 || break; cd $D/t3; mkdir -p v1/v2; for i in $(seq 0 99); do touch v1/v2/f$i; mkdir v1/v2/d$i; done; trinity -C 2 -N 100000 -V $D/t3/v1/v2 -q; echo; echo " done"; echo; sleep 4; done
it tooks just few minutes till the KVM machine (32 bit stable Gentoo Linux, 2040 MB RAM assigned, 512 MB tmpfs) gives this :

With BTRFS it would took much longer - so I'm wondering why ext4 needs so much more memory.

No idea; can you grab /proc/slabinfo and /proc/meminfo every minute or
so until it oom kills trinity? Maybe that will give us a hint of at
least where the memory is getting consumed.
It could be the extent status tree cache, for which the need for a
better shrinker is a known bug that we're working on, but that's just
a wild guess.
Thanks,

Tried to collect it (started trinity at 21:11), but the virtual machine crashed before at 21:55., nothing was logged BTW.
But I'm pretty sure the free memory was gone, b/c the value LowFree was drastically reduced (7 files attached)
