Abstract: A system and method for providing two or more contending processes with concurrent access to a shared resource having a primary list of elements and a list access count, with direct association between at least first and second consecutive elements each having a use counter, wherein resource access includes an obligation to perform an access completion operation. The method comprises the steps of marking the first element as ready to be deleted upon receiving a signal from a traversing one of the contending processes. Next, the first element ready to be deleted is placed on a delete list, is unchained from the primary list and is moved the delete list to an unchained list.
