I've been learning how to use Massif, a tool in valgrind for memory profiling. It quickly paid off!
I discovered that difftastic sometimes attempts to preallocate absurd amounts of memory.
Refactored some unsafe FFI code to be idiomatic Rust today, and valgrind approves of everything on the first run. I'm impressed!
Apparently valgrind rhymes with pinned, not find: http://t.co/3N8aLDvbfr -- I've been saying it wrong all this time!
