I am going to be changing our rfork implementation in the following ways: Rename RFMEM to RFSHMEM, implying that we are fully sharing memory. Also implying that we don't support RFMEM in the same way as other OSes might. Add an additional argument to rfork(2) to support specifying a new stack address in the child. This argument is meaningful only if RFSHMEM is specified. This mod will eliminate some potential timing windows when the child is running with the parents stack. It will also eliminate the need for certain "gymnastics" in code that uses rfork with RFSHMEM. I'll be committing the changes tonight, so let me know if anyone has problems with the concept. -- John dyson@freebsd.org jdyson@nc.com
