Concurrent bugs are especially hard to debug, because many of them do not always show up. There can be many things that make a bug hard to fix, not being [...]
Testing concurrent problems, such as data races, deadlock and so on, could be very hard. This kind of problems only happen with certain input and highly depend on how threads/processes are scheduled. In order to have good coverage of threads/processes schedules, people need to run the same testing many times and keep their fingers crossed [...]
