We do some VCS-status processing in the background so that, if an exception occurs, we already have the file-modification information we need to decide if Sentry should receive the event. This processing can take a few seconds, especially if on a feature branch with uncommitted changes. This patch resolves the case where the Mach command finishes extremely quickly, but the VCS check takes longer. Python waits for all non-daemon processes, so by marking it as a `daemon`, Python now exits immediately once the main thread completes.

==== mach ==== Mach (German for *do*) is a generic command dispatcher for the command line. To use mach, you install the mach core (a Python package), create an executable *driver* script (named whatever you want), and write mach commands. When the *driver* is executed, mach dispatches to the requested command handler automatically. To learn more, read the docs in ``docs/``.
