Fossil is designed to run a single operation quickly, then quit and let the operating system clean up the mess. Even commands like "fossil ui" operate by having the parent process start up a new short-lived child process to process every HTTP request. This idea of starting a new process to handle each operation seems to be seems to be unfamiliar many newer programers. Everyone these days just assumes that a process is long-lived and handles multiple operations. Having a long-lived process is perhaps a good idea if you are building massive applications using a complex "framework" with dozens or hundreds of dependent libraries, since start-up costs can be expensive. But Fossil is self-contained and has minimal start-up cost, and so kicking off a new process to handle each operation really isn't such a bad thing. And it certainly makes programming easier, since you are free to hold program state in global or static variables and you no longer have to worry so much about leaking resources.
