Fill the pool with the workers a parallel load of fileSizeMB will use (its
geometry workers plus the pre-pass worker), each with the engine
instantiated from the shared compiled module. Call it as soon as a load is
requested, so the spawn overlaps the file read. Resolves to the number of
workers started (0 when the pool is off, already holds them, or the module
could not be compiled: the load then spawns as before).
