If you're going to be compiling code, you almost certainly don't want to be using subprocess for this. A view should be able to return in milliseconds. Very few native code compilations are going to be complete in milliseconds.
What you should be doing is treating the compilation step as a compilation task: 1) User submits code for compilation. This creates a compilation task in state "Pending" 2) A second process, completely external to your web server sits waiting for new "pending" tasks; when a new task arrives, it is taken off the queue, and moved to a "compiling" state. 3) The user has the ability to refresh the status of the tasks they have submitted. This could be auto-refreshed, or left as something that the user can hit reload to see the current state. 4) When the compilation completes, the state moves to "Done", and the user can see the result. This external process is called a task queue; there are lots of ways of managing this; two relatively easy options are RQ (a simple Redis-based queue) and Celery (a more complete option; harder to get going, but more reliable and configurable under heavy load). Also - as a security warning - if you're going to be exposing the ability to compile code on the internet, be prepared to be exploited. Compilers can do lots of things, and you're going to be giving permission to compile arbitrary code to anyone who can submit a compilation task. You will need to be *extremely* careful about how you set up the compilation tools to make sure they are adequately sandboxed.
