[Zope] BoboPOS file locking

Right now, if the database is locked by a process, no other process can (or should for fear of curruption) access it. I was wondering if there is any progress on making BoboPOS databases accessible from multiple processes? Is anyone working on addressing this at all? I know I've brought this up on this list before, but never quite got a definitve answer... :) Grisha Trubetskoy
