Yes, I'm still considering switching GCs anyway, but I wanted to know
what happened exactly (and whether it was really a GC issue, which
wasn't 100% obvious).
While doing this, I remembered that Valgrind can't be used with BDW-GC,
which can be annoying. I'll email the GC list about that.

Agreed.

Yes.
