IMHO, Bart's solution would make more sense. Hi John, In case this would not be clear, I really appreciate your work and the time you have spent on analyzing this issue and preparing a solution. Personally I prefer the solution to clear request pointers immediately after these have been freed since that approach results in simpler code and (hopefully) in code that will be easier to maintain.
