That's what I already mentioned in my first mail is what I used to fix
the problem.
Here are some 'hard' numbers, FWIW:
- both ~/scr and swap are on the same SSD;
$ free
total used free shared buffers cached
Mem: 3996748 3800828 195920 0 377176 1078848
-/+ buffers/cache: 2344804 1651944
Swap: 2097148 169760 1927388
git only used up to about 100 MB of VIRT or RSS when I checked, there
was an ulimit of "-S -v 1200000".
- this is git version 1.7.10.4 (1:1.7.10.4-1+wheezy1 i386 Debian)
- after my attempted merge (which had conflicts and I had then
cancelled by way of git reset --hard), and then a "git gc", the times
were:
~/scr$ time git log --raw > _THELOG
