Module Picos_lwt_unix

run_fiber fiber main runs the main program as the specified fiber as a promise with Lwt as the scheduler using a Lwt_unix based System module. In other words, the main program will be run as a Lwt promise or fiber.

⚠️ This may only be called on the main thread on which Lwt runs.

run main is equivalent to calling run_fiber with a freshly created fiber and main wrapped to capture the result of main.

The optional forbid argument defaults to false and determines whether propagation of cancelation is initially allowed.
