Thanks, I've used that (and 'info symbol') to search for a couple more
sources of nondeterminism. So far I've found:
- various jmp_buf objects; these can most likely be zeroed out before
dumping
- gl_state; could also be zeroed
- consing_since_gc; Fdump_emacs could just call Fgarbage_collect to reset
it (though I'm wondering why this difference exists; AFAIK the garbage
collector should be pretty deterministic)
