Correct. In one of the previous mails i suggested a debug mode that
switches it all to pthread rwlocks.
We do not want to lose the identify of what the read paths are: this
could grow into a BKL-alike nasty-to-fix assumption over a couple of
years! Then if someone finds a usecase that intensifies the frequency
of one of the key writepaths, we'll be in trouble ...
