Transactional programming promises to substantially simplify the development and maintenance of correct, scalable, and efficient concurrent programs. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. Unfortunately, conventional debugging programs are often inadequate when employed in relation to code that employs transactional memory and new or modified techniques are needed. Implementations of delayed breakpoints are described that provide programmers with the benefits of breakpoints in transactional code, while minimizing the side-effects of breakpoints placed inside atomic block.
