System and program product for implementing single threaded optimizations in a potentially multi-threaded environment

A program product stored on a recordable medium for implementing single threaded optimizations in a potentially multi-threaded environment, which when executed, comprises:

• means for examining program code for characteristics indicative of a potential to generate multiple threads;
• wherein the examining is performed dynamically as the program code is running allowing the method to be refined;
• wherein the method is refined by at least one of reducing a number of situations that prevent single threaded optimizations from being implemented and delaying correction of single threaded optimizations that have been implemented;
• means for implementing at least one single threaded optimization if the means for examining reveals that the program code does not have the potential to generate multiple threads;
• and
• means for removing the at least one single threaded optimization if the program code is later revealed to have the potential to generate multiple threads.
