I see, that makes even more sense now why it's broken with you. :)

mmap_no_write=yes is needed for OpenBSD, which is pretty much the only
UNIX kernel left where mmap() and write() conflict with each others and
makes things a mess. This is the default when compiled for OpenBSD, so
you just shouldn't have uncommented the line and everything should have
worked.

mmap_disable=yes is for completely disabling mmap()ing, and also
introduces some other changes to allow shared filesystems to work (NFS,
clustered filesystems, etc.)
