Max, I think what will happen is that we will mark further uses
or read locks as recursive as "not supported", perhaps witness
can temporarily grow a flag to ignore recursive read ops until
the existing infrastructure is fixed.

I will not get into alternatives for pfil, as it seems you've mostly
worked it out.
