👉 In the context of computer science, "cosuretyship" refers to a type of program that is designed to be able to execute multiple threads concurrently on a single machine. This is achieved by using synchronization primitives such as locks or semaphores. The goal of cosuretyship is to ensure that all threads are synchronized and can access shared resources at the same time, without causing any race conditions or deadlocks. This is important for applications where multiple threads need to access and modify data simultaneously
