Comment (by mascguy):

 Replying to [comment:2 jmroot]:
 > There is never any guarantee what order multiple pre- or post- phase
 blocks will run in, so anything that relies on them running in a
 particular order is broken. If gramps needs something to be done before
 some post-destroot block runs, it needs to do it somewhere that runs
 earlier like destroot or pre-destroot.

 Hmmm, I thought that `post-destroot` blocks are run in a deterministic
 manner, based on the order in which they're registered.

 So that's not the case?
