Compile a module in a separate compiler instance and read the AST, returning true if the module compiles without errors, using a lock manager to avoid building the same module in multiple compiler instances.
Uses a lock file manager and exponential backoff to reduce the chances that multiple instances will compete to create the same module. On timeout, deletes the lock file in order to avoid deadlock from crashing processes or bugs in the lock file manager.
