(In #5404) Replying to andreasf:

Yes. There's a Makefile variable NO_MMAP but I don't set it, so it will use mmap at some point.

Thanks, that supports my suspicion that this is indeed the same problem as #5409 where an mmap()ed area is deleted while the page writer writes back one of its modified pages.

@jahaiku: Sorry for removing you from the CC. Trac is really annoying w.r.t. concurrent ticket changes.
